Question 82Electricity & Electronics - QMED
70% to passWhat will be the resulting current when a voltage of 115 VDC is applied to a resistance of 12 ohms in figure "A" of the illustrated circuit with the switch closed? Illustration EL-0018
A1.24 amps
B9.58 amps
C104.34 amps
D127 amps
AI Explanation
The correct answer is B) 9.58 amps. The reasoning is based on Ohm's law, which states that the current (I) flowing through a resistor is equal to the voltage (V) divided by the resistance (R). In this case, with a voltage of 115 VDC and a resistance of 12 ohms, the current can be calculated as I = V/R, which equals 115 V / 12 ohms = 9.58 amps. The other options are incorrect because: A) 1.24 amps is too low, as it does not match the calculation. C) 104.34 amps is too high, as it does not match the calculation. D) 127 amps is also too high, as it does not match the calculation.
