Question 81Electricity & Electronics - QMED
70% to passIf the voltage supplied to the lighting circuit is 110 volts, how much current is drawn by a 100 watt light bulb?
A0.08 amps
B0.91 amps
C1.10 amps
D90.9 amps
AI Explanation
The correct answer is B) 0.91 amps. To calculate the current drawn by a 100 watt light bulb on a 110 volt circuit, we can use the formula: Current (I) = Power (P) / Voltage (V). Plugging in the values, we get: I = 100 watts / 110 volts = 0.91 amps. The other answer choices are incorrect because: A) 0.08 amps is too low for a 100 watt bulb on a 110 volt circuit. C) 1.10 amps is slightly too high. D) 90.9 amps is way too high and would represent a dangerously high current draw.
