Text Solution

Verified by Experts

Electric power: It is the rate at which an electric appliance converts electric energy into other forms of energy. Or, it is the rate at which work is done by a source of emf in maintaining an electric current through a circuit.
`P=(W)/(t)=VI=I^(2)R=(V^(2))/(R )`
Elecric energy: It is the total workdone in maintaining an electric current in an electric circuit for a given time.
`W=Pt=VI t" joule"=I^(2)Rt" joule".`
