A28.25 amps
B35.32 amps
C354.16 amps
D443.62 amps
AI Explanation

The correct answer is C) 354.16 amps. This is calculated using Ohm's law, which states that the current (I) in a circuit is equal to the voltage (V) divided by the resistance (R). The formula is I = V/R. Plugging in the values given, we get I = 442.7 V / 1.25 ohms = 354.16 amps. The other answer choices are incorrect because they do not properly apply Ohm's law to the given circuit parameters. Choices A, B, and D do not accurately calculate the current when a 442.7 VDC voltage is applied across a 1.25 ohm resistance.
