What is the source voltage in a circuit that consumes 1,200 watts at a current of 5A?

To determine the source voltage in the circuit, we can utilize the power formula that relates voltage (V), current (I), and power (P):

[ P = V \times I ]

In this case, we know the power consumption is 1,200 watts, and the current is 5 amps. We can rearrange the formula to find the voltage:

[ V = \frac{P}{I} ]

Substituting in the known values:

[ V = \frac{1200 \text{ watts}}{5 \text{ amps}} ]

Calculating this gives:

[ V = 240 \text{ volts} ]

This outcome indicates that the source voltage in the circuit is 240 volts. Understanding this relationship is foundational in electrical calculations, as it allows one to determine how voltage, current, and power are interconnected in various electrical systems.

The other options provided do not satisfy the equation when substituting the given power and current values, resulting in values that do not correctly represent the conditions stated in the question.
