An AC circuit with a resistance of 10 ohms and a current of 10 amps would have what total wattage?

To determine the total wattage in an AC circuit, you can apply the basic formula for electrical power, which is calculated as the product of voltage and current, or alternatively as the square of the current multiplied by resistance. In this case, using the second approach, the formula is:

Power (P) = Current (I)² × Resistance (R).

Given that the current (I) is 10 amps and the resistance (R) is 10 ohms, you would calculate the power as follows:

P = 10 amps × 10 amps × 10 ohms = 1000 watts.

This calculation shows that the total wattage in the circuit is indeed 1000 watts, confirming that the correct answer is accurate. Understanding this formula is essential in electrical work, as it allows for quick calculations of power under various conditions, tracking power consumption, and ensuring equipment operates within safe limits.
