(a) A current of `1 A` flows in a series curcuit containing an electric lamp and a conductor of `5 Omega` when connected to a `10 V` battery. Calculate the resistance of the electric lamp.
(b) Now if a resistance of `10 Omega` is connected in parallel with this series combination, what change (if any) in current flowing through `5 Omega` conductor and potential difference across the lamp will take place ? Give reason.

Explanation

To solve the given problem step by step, we can break it down into two parts as per the question.

### Part (a): Calculate the resistance of the electric lamp.

1. **Given Data**:
- Current (I) = 1 A
- Voltage (V) = 10 V
- Resistance of the conductor (R_conductor) = 5 Ω
