Question

A lamp of resistance 20 ohm and a conductor of resistance 8 ohm connected with a battery of 8 ohm in series .calculate the :
1. Total resistance in the circuit
2. Current flowing through the circuit

Answer 1

36 ohm is the total resistance to find current in the circuit u have to give voltage. Having the voltage using ohms law V=IR you can calculate current

Answer 2

36 is the total resistance to find current in the circuit you  have to give voltage.

Having the voltage using  law V=IR you can calculate current
