Question

Simple Circuit and Ohm's Law Check-for-Understanding
A circuit consists of a resistor and a battery. Increasing the potential difference of the battery while
keeping the temperature of the circuit constant would result in an increase in
neither current nor resistance
O current, only
O both current and resistance
resistance, only

Answer 1

Current only.

(But in the real world, also power supplied by the battery, power dissipated by the resistor, temperature of the resistor, and temperature of the air around the resistor.)

Answer 2

When the potential difference is increases. Then, only current is increases.

Option B is correct.

Ohm's law:

The potential difference across two terminal of wire is directly proportional to current flowing through it.

                    V = IR

Where,

V is potential difference

I is current and

R is resistance.

Since, the potential difference is proportional to current. therefore, when increasing the potential difference then current is also increases.
