There are two types of current electricity; Direct Current and Alternating Current.
When to the on-off switch on the potential energy (voltage) is built up on one end of the wire which forces the electrons to flow to the other side where the area of positive charges are. In the end, it causes the bulb to light up.
“The polarity of the voltage across the wire coils reverses as the opposite poles of the rotating magnet pass by. Connected to a load, this reversing voltage polarity will create a reversing current direction in the circuit. The faster the alternator's shaft is turned, the faster the magnet will spin, resulting in an alternating voltage and current that switches directions more often in a given amount of time. “
In order to find voltage, resistance, and current for both AC and DC, one could use voltmeters.
Voltages=V= I x R
Current= I= V/R
Resistance= R= V/I
