Question

The relationship between the potential difference and the current iii a conductor is stated in the form of a law. 

1. Name the law. 

2. What does the slope of V-I graph for a conductor represent? 

3. Name the material used for making the connecting wire

Answer 1

1. The relationship between the potential difference and the current in a conductor is given by Ohm’s law. 

2. The slope of the V—I graph gives the resistance of the conductor. 

Slope R = v/I = R

The material used for making connecting wires is copper.
