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.
