An ammeter of resistance 1 Ohm can measure current upto 1.0 A. (i) What must be the value of the shunt resistance to enable the ammeter to measure upto 5.0 A? (ii) What is the combined resistance of the ammeter and the shunt?

Explanation

To solve the problem step by step, we will address each part of the question separately.

### Part (i): Finding the Shunt Resistance

1. **Understanding the Setup**:
- An ammeter with a resistance \( R = 1 \, \Omega \) can measure a maximum current \( I_G = 1 \, A \).
- We want to modify this ammeter so that it can measure a total current \( I = 5 \, A \).
