Expert Answer:
In DC circuits, there is no frequency component, potential difference, measured in volts. Hence, we represent potential difference as a scalar.
In AC circuits, the frequency element, the voltage current remains to be out of phase to each other due to frequency-related component and the oppositions of wires. In such a case, we represent potential difference as a vector, having a real and imaginary component.

- why does need to maintain the current in a given electric circuit by expanding its energy stored in it?
- The flow of electrons is opposite to the direction of the flow of current as electron is negatively charged . Then why current is defined as the flow of electrons through the conductor though current travels from positive to negative terminal.
- If charge on one electron is 1.6 x 10 -19 C. Calculate number of electrons required to constitute 1A of current in 1s.

Why can't I use P=VI here, and how can I determine when to use P=VI or P=I^2 R or P=V^2 / R
