What is the current of a 120-volt circuit with a 1440-watt load?

• A. 8 amperes
• B. 10 amperes
• C. 12 amperes
• D. 14 amperes

Answer: (C)

To find the current of a 120-volt circuit with a 1440-watt load, you can use the formula derived from Ohm's Law, which relates power (P), voltage (V), and current (I): \[ I = \frac{P}{V} \] In this case, the power (P) is 1440 watts and the voltage (V) is 120 volts. Plugging in the values, you have: \[ I = \frac{1440 \text{ watts}}{120 \text{ volts}} \] Calculating this gives: \[ I = 12 \text{ amperes} \] This calculation shows that the correct answer is 12 amperes. This value represents the current flowing through the circuit under the given load conditions, reflecting a direct application of electrical principles to solve for current in a circuit using the basic relationship among power, voltage, and current. The other options (8, 10, and 14 amperes) do not satisfy the power requirements for the given voltage and load. Thus, they are not correct.

To find the current of a 120-volt circuit with a 1440-watt load, you can use the formula derived from Ohm's Law, which relates power (P), voltage (V), and current (I):

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

In this case, the power (P) is 1440 watts and the voltage (V) is 120 volts. Plugging in the values, you have:

[ I = \frac{1440 \text{ watts}}{120 \text{ volts}} ]

Calculating this gives:

[ I = 12 \text{ amperes} ]

This calculation shows that the correct answer is 12 amperes. This value represents the current flowing through the circuit under the given load conditions, reflecting a direct application of electrical principles to solve for current in a circuit using the basic relationship among power, voltage, and current.

The other options (8, 10, and 14 amperes) do not satisfy the power requirements for the given voltage and load. Thus, they are not correct.
