Question

A: if the graph is plotted between potential difference and current, then it will be the straight line from the origin.

R: the current is directly proportional to the current

both A and R are true and R is the correct explanation of R.

both A and R are true and R is not the correct explanation of R.

A is true but R is false.

A is false but R is true.

A: longer wire has greater resistance and the smaller wire has lesser resistance.

R: resistance is inversely proportional to the length of wire.

both A and R are true and R is the correct explanation of R.

Answer 1

Explanation:

Explanation: f a graph is plotted between the potential difference and the current flowing, the graph is a straight line passing through the origin. Reason(R): The current is directly proportional to the potential difference.
