Question

Let us consider the current flowing through a metallic wire if the temperature of the entire system increases. What will happen from the following options? Give reason.
(a) Potential difference (V) increases (b) Resistance (R) decreases
(c) Potential difference (V) decrease (d) V and R remains the same

Answer 1

Answer:

The potential difference between two points is said to be 1 V if 1 Joule of work is done in moving ... If length increases resistance will also increase .

Answer 2

Answer:

Option A

Explanation:

Potential difference increases

As resistivity increases on increasing temperature by this resistance will also increases

so by ohms law Potential difference increases.
