Question

If the voltage across a conductor is increased while its temperature remains unchanged, what happens to the current flowing through it?

Options

• The current decreases in the same ratio

• The current first increases and then becomes zero

• The current increases in the same ratio

• The current remains unchanged

Answer 1

If the conductor and its temperature remain unchanged, increasing the voltage increases the current in the same ratio. This direct proportionality between voltage and current is the essence of Ohm's Law.
