(V): So amps are equal to watts divided by volts. HSPF Rating: What Is A Good HSPF Rating For Heat Pumps? This watts to amps calculator (also known as amps to watts calculator or amperage calculator) helps you understand how to calculate watts of a circuit depending on the type of the current. What is the current in amps when the power consumption is 330 watts and the voltage supply is 110 volts? By the way, you can always control the value of the voltage you want to deliver to your devices. The phase current I in amps (A) is equal to the real power P in watts (W), divided by square root of 3 times the power factor PF times the line to line RMS voltage V L-L in volts (V): I (A) = P (W) / (√ 3 × PF × V L-L (V)) According to the Watt’s Law the total power of the circuit is equal to the product of the current and voltage of the circuit. An example of direct current would be a battery powered torch. Ampere is the SI unit of electric current represented as 'A'. times volts. Watts is also known as volt-amps and is typically used in conjunction with AC power circuits. If we input the P = 500 Watts and V = 120 Volts, we get: I = 500 Watts/120 Volt = 4.17 Amps We assume the power factor to be of the value 0.9. DC stands for direct current, when the current flows in one single direction. The power factor is a measure of the efficiency of AC currents since they are represented by single phase sine wave. They measure the force required to make the electrical current (amps) flow. In the end, you will also find a watts-to-amps table at 120V electric potential. When solving for DC currents, leave the power factor section blank. AC three phase watts to amps calculation formula Amps calculation with line to line voltage.

Let's look at these conversions a little more closely. it uses increased water volume and higher water pressure; the same applies to the wattage if amps and volts are increased. You can calculate amps from watts and volts. Watts to amps is a watts to amps converter. The formula for Watt’s law stays the same, just as long as you express the wattage in watts (your sum will go wrong if you use ‘5W’ to It can be helpful to imagine electrical current as water in a hose. In the hose analogy, the volts would be the water pressure. (Electricity Calculator). They are described in detail in the next section. A three-phase current is usually applied in the electricity networks that are connected to our houses. If you have any problems using this watts and amps converter, please contact me. Disclaimer: Whilst every effort has been made in building this calculator, we are not to be held Volts are the measurement used to determine how much force is needed to cause the electric current to flow. The current I in amps (A) is equal to the power P in watts (W), divided by the voltage V in volts Power supplied to homes and businesses uses AC supply. You can calculate Amps using the relationship between Amps, Volts and Watts. To convert electrical power to electrical current (Watts to Amps), we need to use the electrical power equation: Using this equation, we can convert watts directly to amps, if we know the voltage. (2 Examples), 7 Best Tankless Water Heaters In 2020 (Based On Specs), How Do Portable Air Conditioners Work? It’s 5 Amps. To find the amps, you work backwards with Watt’s Law and divide the wattage by the volts: Current = Power ÷ Voltage Watts. Electric current can also be a source of power P so that it can release or transport some energy. Save my name, email, and website in this browser for the next time I comment. It convert units from watts to amps or vice versa with a metric conversion table. Example 1. In cases with higher wattage, it’s not unusual to use a higher 220 voltage. You may opt out of receiving email updates at any time by using the unsubscribe link in the emails. (V): So amps are equal to watts divided by power factor In the end, you will also find a watts-to-amps table at 120V electric potential. The phase current I in amps (A) is equal to the real power P in In keeping with the earlier example, you could think of volts as the water pressure in the hosepipe, which makes the water flow. EasyUnitConverter.com. AC stands for alternating current, when the current periodically changes direction. Please help me spread the word by sharing this with friends or on your website/blog. Amps are amperes, a unit which measures electrical current. What Size Of Dehumidifier Do I Need? Basement Dehumidifier Setting: 30%, 40%, 50%, or 60% Humidity? The phase current I in amps (A) is equal to the power P in watts (W), divided by square root of 3 times the power factor PF times the line to line RMS voltage V L-L in volts (V): I (A) = P (W) / (√ 3 × PF × V L-L (V)) The power factor of resistive impedance load is equal to 1. All of these units from volts and amps to watts describe the voltage, amperage, and power respectively since they are shorter and easier to be pronounced. Example: An air conditioner is powered by 800 Watts. mean ‘5KW’; you need to use 5000W instead). Mind The Gap - Are You Recall Ready To PAS 7100? In fact, this question is not precise enough - you should ask: "How to convert volts and amps to watts?" liable for any damages or monetary losses arising out of or in connection with the use of it. times the line to line RMS voltage VL-L in volts Privacy Policy | This calculator works on the assumption of daily use, followed by a full recharge. However, in alternating current (AC) the electric current changes direction at 50 times per second (50 Hz or hertz) in the UK supply. The labels ‘AC’ and ‘DC’ are used to describe the types of current flow in a circuit. Example 2. Let’s say we have a 500W air conditioner plug into 120 V voltage. I is electrical current or amperage, measured in Amps (A). (Includes Calculator).

Delta connection - referring to Line-to-Line Voltage (VLL). watts (W), divided by 3 times the It varies from 0 to 1. What Size Generator To Run 5 Ton AC Unit? Current = Power ÷ Voltage Alternating current (AC) is used to supply things like houses and buildings and mains connected appliances. In terms of the hosepipe example, this would refer to the amount of water being released. The standard voltage for the majority of electrical devices is 110-120V and upgraded voltage powerful electric devices use is 220V. Asia, the current changes direction 50 times per second, which is 50Hz. But if you plug such a device into 220 V, the current that is generated is only 13.64 Amps (there is no need for amp breakers). The SI unit of voltage is a volt, the unit of amperage is an ampere (usually shortened to amp), and the unit of power is a watt. Watts To Amps Converter (With 120V Examples), 5 Simple Yet Effective Ways Of How To Improve Indoor Air Quality, Where To Place Air Purifier? How Much Does It Cost to Run An Air Conditioner (Per Hour)? The more water flowing through the hosepipe, the stronger the current is. Watts represent the amount of energy produced by the amps and volts working together. To answer it, you'll first need to know what kind of current you're dealing with. Here you can easily convert watts to amps using this calculator: In order to demonstrate how watts can be converted to amps, we solved a few examples for how many amps is 500 watts, 1000 watts, and 3000 watts. Find out how to convert Amps to Watts here or how to calculate Ohm's Law here. For DC Currents: I = P / V. Where I is the current (amps) P is the power in Watts; V is the voltage in volts; For AC Currents: I = P/ (V*PF) Where I is the current (amps) P is the power in watts; V … The Calculator works on the Watt’s Law formula given below: Power (P) = Voltage (V) x Current (I) Watt’s Law. of 3 times power factor times volts. It tells us about the ratio between the real power, which does the work, and the one supplied to the circuit. CADR Rating: What It A Good CADR Rating For Air Purifier? For 25 Amps, for example, you would already need an amp breaker. Amps multiplied by Volts equals Watts, which is the measurement used to determine the amount of energy. How Do Air Purifiers Work? Current = 2400W ÷ 120V AC and DC power systems You can't convert watts to amps since watts and amps units do not measure the same quantity.
