Which factor does NOT affect the electric power consumed by an electric device?
-
A.
Frequency of the device
-
B.
Resistance of the device
-
C.
Voltage applied to the device
-
D.
Current passing through the device
Correct Answer:
A. Frequency of the device
Explanation:
The correct answer is Option A: Frequency of the device.
Electric power (P) consumed by a device is determined by the relationship between voltage (V), current (I), and resistance (R), commonly expressed through formulas such as P = VI or P = I²R. While the voltage applied, the current flowing through the circuit, and the internal resistance of the component directly dictate how much energy is transformed, the frequency of the electrical supply does not inherently change the power consumption of a purely resistive device. Frequency relates to the number of cycles per second in alternating current (AC) but is not a variable in the fundamental power calculation for standard electrical consumption. Therefore, among the given choices, frequency is the factor that does not affect the electric power used.
