A voltage source of a circuit provides 240 volts and draws 48 amps. How much resistance is in the circuit?

Explanation:
To determine the resistance in the circuit, the formula derived from Ohm's Law can be applied, which states that Voltage (V) = Current (I) x Resistance (R). Given that the voltage source is 240 volts and the circuit draws a current of 48 amps, you can rearrange the formula to solve for resistance: R = V / I. Substituting the known values into the equation: R = 240 volts / 48 amps = 5 ohms. This calculation confirms that the resistance in the circuit is indeed 5 ohms, making it the correct answer.
