How much power is consumed by a 24VDC circuit drawing 2A?

The correct answer is: 48W

To determine the power consumed by a circuit, you can use the formula: Power (P) = Voltage (V) x Current (I) In this case, the voltage of the circuit is 24 volts, and the current being drawn is 2 amps. By applying the formula: P = 24V x 2A Calculating this gives: P = 48 watts Thus, the correct answer is 48W, as it accurately represents the power consumption based on the given voltage and current values. This understanding is essential for applying electrical principles to practical scenarios like those encountered in locksmithing tasks involving electronic locks or access control systems.
