Question

A current of 1 ampere flows through a series circuit comtaining an electric lamp and a conductor of 5 ohm when connected to a 10 volt battery. Calculate the resistance of the electric lamp

Answer 1

let R ohm be the resistance of lamp.

Total resistance =(5+R )ohm

V=IR

R=V/I

5+R=10/1

R=10-5=5ohm *answer *
