b. A parallel circuit with two paths. A single 12 V cell powers the circuit. On one branch is a resistor and a switch. On the second branch is a single light bulb . The total current of the circuit is 6 A . What is the total resistance of the circuit? marks)

1. **Find the total resistance:**We know the total voltage (V) and the total current (I) of the circuit. We can use Ohm's Law (V = IR) to find the total resistance (R).* Rearrange Ohm's Law to solve for R: R = V/I* Substitute the given values: R = 12V / 6A* Calculate: R = 2 OhmsTherefore, the total resistance of the circuit is .
