How much current is drawn by a 120V circuit containing a 1,500W load?

• A. 10A
• B. 12.5A
• C. 15A
• D. 20A

Answer: (B)

To determine the current draw of a circuit, you can use the formula derived from Ohm's Law, which states that Power (in watts) equals Voltage (in volts) multiplied by Current (in amperes). This can be expressed as: Power (P) = Voltage (V) x Current (I) Rearranging the formula to solve for current gives: Current (I) = Power (P) / Voltage (V) In this scenario, you have a 1,500W load on a 120V circuit. Plugging these values into the rearranged formula will yield: Current (I) = 1,500W / 120V = 12.5A Therefore, a current of 12.5 amps is drawn by the circuit, which corresponds to the correct answer. This calculation is essential for ensuring that circuits are not overloaded and that suitable circuit protection is in place to prevent equipment damage or fire hazards.

Therefore, a current of 12.5 amps is drawn by the circuit, which corresponds to the correct answer. This calculation is essential for ensuring that circuits are not overloaded and that suitable circuit protection is in place to prevent equipment damage or fire hazards.
