The equivalent resistance of three 12-ohm resistors in parallel is 4 ohms. With a 12 V source, what is the total current drawn by this network?

Explanation:
In parallel circuits, the voltage across each resistor is the same and the total current is the sum of the currents through each branch. The equivalent resistance of three 12-ohm resistors in parallel is 12/3 = 4 ohms. With a 12 V source, the total current drawn from the source is I = V / R_eq = 12 / 4 = 3 amperes. You can also verify by each resistor drawing I_branch = V/R = 12/12 = 1 A, so the total is 3 A.
