An electric resistor of resistance $12\Omega$ is connected across a $36\text{V}$ supply. Calculate the electric current flowing through the resistor.

Step-by-step solution

1. Use Ohm’s law $V=IR$.
2. Rearrange to find $I=V/R$.
3. Substitute the given values: $I=36\text{V}/12\Omega$.
4. Calculate the quotient: $I=3\text{A}$.
