A 24VDC circuit drawing 2A consumes how many watts?

A 24VDC circuit drawing 2A consumes how many watts?

• A. 24W
• B. 48W
• C. 72W
• D. 96W

Answer: (B)

Power in a direct current circuit is found by multiplying the voltage by the current (P = V × I). So with 24 volts and a current of 2 amperes, the power drawn is 24 × 2 = 48 watts. If you think about the other numbers in the options, they would require different currents: 24 watts would come from 24V at 1A, 72 watts from 24V at 3A, and 96 watts from 24V at 4A. The 48-watt result matches a 24V supply with a 2A draw.
