Voltage
an electromotive force or ability difference expressed in volts. Potential to do work.
Direct Current (DC)
Electric modern-day that flows in simplest one direction
Alternating Current (AC)
A float of electric charge that frequently reverses its route. Bidirectional.
Wattage
the electrical electricity fed on by a device.
Coulomb
the SI unit of electrical charge, same to the quantity of strength conveyed in one second with
the aid of a present day of 1 ampere.
1 amp = 1 coulomb/sec
1 amp = 6.25 x 10 (18)
