Kcl Kvl In Ac Circuits

To determine the average power dissipated over a cycle in an AC circuit, we have to consider the voltage and current waveforms and their phase difference.

Given the equations:

• V
• mA

We need to convert the current from milliamps to amps for consistency in units:

• A

The formula for the average power in an AC circuit is given by:

Where:

• is the phase difference between voltage and current.

Calculating the RMS values:

• V
• A

Given that the phase difference , we find:

Now, substitute these values into the average power formula:

• W

Therefore, the average power dissipated in one cycle is 2.5 W.
