Question

Resistance is calculated as the ratio of which two quantities, according to Ohm's law?

Options

• Current to Power

• Voltage to Current

• Current to Voltage

• Power to Voltage

Answer 1

Voltage to Current

Explanation:

According to Ohm's law V = IR, resistance R = \[\frac {V}{I}\]​, i.e., the ratio of voltage (V) across a wire to the current (I) passing through it. This is the fundamental principle used in resistance measurement experiments.
