Power in a Circuit

Resistance: Resistance in a circuit refers to how much opposition there is to the flow of electric current. It determines how much voltage is needed for a given amount of current.

Ohm's Law: Ohm's Law states that the current passing through a conductor between two points is directly proportional to the voltage across those two points, and inversely proportional to the resistance between them.

Electric Energy: Electric energy refers to the ability of an electric charge to do work. It can be converted into other forms of energy, such as light or heat.
