Question 81Electricity/Electronics - QMED70% to pass
If the voltage supplied to the lighting circuit is 110 volts, how much current is drawn by a 100 watt light bulb?
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.
