What is the power in an AC circuit?

The power consumed by the load in an AC circuit is proportional to the product of the instantaneous voltage, instantaneous current and the power factor. The instantaneous power varies continuously. The transfer of energy over a time period is proportional to the average power consumed by the load. The voltage and current values used are the arms vaues.

How to Calculate AC Power?

AC Power calculator uses Power=Voltage (total)*Current (total)*cos(Phi) to calculate the Power, The AC Power formula is used to calculate the total power consumed by the load in an AC circuit, where current lags voltage by a phase of ϕ. Power and is denoted by Powerload symbol.

How to calculate AC Power using this online calculator? To use this online calculator for AC Power, enter Voltage (total) (V), Current (total) (I) and Phi (ϕ) and hit the calculate button. Here is how the AC Power calculation can be explained with given input values -> 5000 = 100*50*cos((0)).

FAQ

What is AC Power?
The AC Power formula is used to calculate the total power consumed by the load in an AC circuit, where current lags voltage by a phase of ϕ and is represented as Powerload=V*I*cos(ϕ) or Power=Voltage (total)*Current (total)*cos(Phi). Voltage (total) is the amount of total potential difference across the network. In this case, it is usually the voltage difference across the voltmeter, Current (total) is the total amount of current flowing through the circuit with the load and Phi is used to calculate cos(phi), which is the power factor.
How to calculate AC Power?
The AC Power formula is used to calculate the total power consumed by the load in an AC circuit, where current lags voltage by a phase of ϕ is calculated using Power=Voltage (total)*Current (total)*cos(Phi). To calculate AC Power, you need Voltage (total) (V), Current (total) (I) and Phi (ϕ). With our tool, you need to enter the respective value for Voltage (total), Current (total) and Phi and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.
How many ways are there to calculate Power?
In this formula, Power uses Voltage (total), Current (total) and Phi. We can use 2 other way(s) to calculate the same, which is/are as follows -
  • Power=(Voltage (total)*Current (total))-(((Voltage (total))^2)/Resistance)
  • Power=(Voltage (total)*Current (total))-(((Current (total))^2)*Resistance)
