Question

# How is voltage related to resistance?

Solution

## VoltageVoltage is also termed the potential difference.Potential difference is defined as the work done in bringing a unit positive charge from one point on a conductor to another point on the same conductor.The unit of potential difference is volt or $V$.ResistanceWhen current flows through a circuit it experiences a resistive force. The parameter that gives the magnitude of resistive force experienced by the current is called resistance.The unit of resistance is ohm or $\Omega$.Ohm's LawAccording to ohms law, the current flowing through a circuit is directly proportional to the voltage across the circuit.Let $V$ be the voltage, $I$ be current, and $R$ be the constant of proportionality, then$V\propto I$or $V=IR$Hence, the relation between voltage and resistance is given above.
