SUMMARY
The discussion focuses on calculating the current through and the potential difference across a 4.0 ohm resistor in a circuit. The current is determined using Ohm's Law (I = V/R), resulting in a current of 6 A when the voltage is 24 V. The total resistance of the circuit is calculated to be 12 ohms, leading to a current of 2 A through the circuit. The potential difference across the 4.0 ohm resistor is subsequently found to be 8 V using the formula V = IR.
