# Is charge measured in amps?

Charge (Q) is measured in coulombs (C). Each electron carries a tiny amount of charge, 1.6 x 10-19 coulombs. Power (P) is the rate at which energy is transformed in a device, it is measure in watts (W). 1 watt means that 1 joule of energy is transformed in one second.

Keeping this in consideration, are current and charge the same thing?

No they are not the same. Simple explanation for these terms can be: Charge: Its the "amount" of unbalanced electricity in a body. Its usually measured in the form of electrons (either excess or deficiency). Current: It is the "flow" of electrons from higher electric potential towards the lower.

How are electric current and electric charge related?

It can also be carried by ions in an electrolyte, or by both ions and electrons such as in an ionised gas (plasma). The SI unit for measuring an electric current is the ampere, which is the flow of electric charge across a surface at the rate of one coulomb per second.
