1. What is the basic unit to measure electrical power?
Hertz - one cycle per second is equal to one hertz. Electricity is caused to flow through wires at a frequency of 60 cycles per second. This means electrons flow one direction - then in the reverse direction - repeating this cycle 60 times every seco
Voltage or electromotive force is pressure required to force electrons into a wire. Voltage is also measured in units called Volts.
E stands for voltage in volts - I stands for current in amperes - and P stands for power in watts.

2. What is DC?
