That means that there is 120V between the phase and neutral wire, and the AC current frequency is 60 Hz. Incandescent 120V bulbs are usually between 60-120W, while LED bulbs are 7-18W. If the circuit features a voltage of 240V and transfers 1000 Watts, then the current is:

How many Amps are 1000 Watts at 240 Volts? Similarly, to find out the voltage of the circuit, we need the circuit's current - for example, if the circuit current is 5 Amp, the circuit voltage is:

P(W) = I(A) * U(V) = 3 Amp * 240V = 720 Watts How many Volts are 100 Watts? If we know the voltage of the electric circuit, to calculate the circuit's power, we must find out the electric current (A) in the electric circuit.įor example, if the current is 3 Amp, the circuit power is: U(V) =P(W) / I(A) How many Watts are 240 Volts? To calculate the voltage in the electric circuit from Watts and Amps, use the following formula:

P(W) = I(A) x U(V) How to calculate Volts from Watts and Amps?

To calculate the power in the electric circuit from Amps and Volts, use the following formula: I(A) = P(W) / U(V) How to calculate Watts from Volts and Amps? To calculate the current in the electric circuit from Watts and Volts, use the following formula: Here are the most common Frequently Asked Questions (FAQ) about electric unit (Volts, Amperes, Watts) conversions: How to calculate Amps from Watts and Volts?

In order to find out exact voltages, currents and wattages, feel free to use our conversion calculators. Similarly, if the load is 3000W or even larger, higher voltages are required in order to keep the current at acceptable levels: Voltage (V) Voltage (V)Īs one can see, if the nominal voltage is increased from 12V to 48V, the current is decreased 4x, leading to a rather acceptable current of 41.66 Amps (from 166.6A!). The following chart lists required Amps and Voltages for the required 2000 watts of power. If You plan on having a 2000 Watts load (power generator, power inverter, UPS device, etc.), it is recommended to know the required current (A or Amps) and voltage (V) - the higher the voltage, the less current is required, leading to thinner cables or less energy loses. In order to convert volts, amps, and watts, feel free to use these conversion calculators - write the values that You have and click 'Calculate' to convert them : Note: these formulas are for either DC (Direct Current) electric systems or for AC (Alternate Current) electric systems using 'effective' values and α=0° (α is the phase angle between voltage and current).Īmps and Volts to Watts and Other Conversion Calculators In order to convert volts, amps, and watts, we need to use these formulas: How to Convert Volts and Amps to Watts and Other Formulas Unit conversions sometimes can be difficult, but with most basic electric units like the voltage, current, and power, things are almost always very simple. Here is simple volts and amps to watts calculator, with short explanations, formulas, and charts.
