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

current is directly proportional to the potential difference across the terminal according to the ohm's law
so
the potential difference will decrease
because we know with the rise in temperature resistibility increases
that is it will obstruct the flow of current and as a flow of current will be of obstructed then the potential difference with the decrease in current will decrease
