WebAnd we can recall that the power dissipated by a resistor is given by the following equation: the power, 𝑃, is equal to the voltage across a resistor, 𝑉, multiplied by the current through that resistor, 𝐼. Happily for us, we already know the current through the circuit. It’s been given to us in the question. It’s four amps. WebSince for resistors in AC circuits the phase angle φ between the voltage and the current is zero, then the power factor of the circuit is given as cos 0o = 1.0. The power in the circuit at any instant in time can be found by multiplying the voltage and current at that instant.
