In a simple resistive circuit with a 9 V source and a 3 Ω resistor, what is the current?

Explanation:
Think about Ohm’s Law for a single resistor circuit. The current through the resistor is found by I = V / R. With a 9 V source across a 3 Ω resistor, the current is I = 9 / 3 = 3 A. So the circuit carries 3 amperes from the source through the resistor. This also reflects how the voltage and resistance relate: higher voltage pushes more current, while higher resistance reduces it.
