In DC, the current flows + to - and direction matters

In AC, the direction does not matter

Voltage is V

Current is I and it can be A amp

Resistance is R and it can be ohm, omega

In series, the current is same but voltage is divided.

In parallel, the current is different but voltage is same.

LED is Light emitting diode
