Question

When a potential difference of 2 V is applied across the ends of a wire of 5 m length a current of 1A is found to flow through it calculate the resistance per unit length of the wire and The resistance of 2 m length of wire and The resistance across the ends of the wire if it is doubled on it self

Answer 1

Answer:

1) 0.4 OHM

2)0.8 OHM

3)IT WILL BE DOUBLED

Step-by-step explanation:

R=V/I

1) 2/5 = 0.4 OHM

2)0.4 * 2 = 0.8 OHM
