Expert Solution

Question 1

Differences between AC and DC currents:

1. DC(Direct Current) ideally has fixed values and does not oscillate between two values, AC on other hand is called Alternating Currents oscillates between two values, usually in form of a sine waveform.

2. DC has 0 frequency, and AC has some finite frequency.

3. Active components like capacitor and inductor behave like Open Circuit and Closed Circuit respectively when DC is passed through them. Whereas capacitor and inductors have impedance and have phase-shifting effects when AC is passed through them.

4. In daily life, AC is encountered in electric wall outlets, whereas DC can be encountered in a circuit connected to any battery.
