Question 435Electricity & Electronics - Assistant Engineer
70% to passAn electrical component is connected across a 120 volt 60 hertz AC supply. What is the current drawn by the component if the impedance is 200 ohms?
A0.01 amperes
B0.60 amperes
C1.67 amperes
D100 amperes
AI Explanation
The correct answer is B) 0.60 amperes. To calculate the current drawn by the component, we can use Ohm's law: I = V/Z, where I is the current, V is the voltage, and Z is the impedance. Given: - Voltage (V) = 120 volts - Impedance (Z) = 200 ohms Plugging these values into the formula, we get: I = V/Z I = 120 volts / 200 ohms I = 0.60 amperes The other options are incorrect because: A) 0.01 amperes is too low C) 1.67 amperes is too high D) 100 amperes is much too high for a 120-volt, 200-ohm circuit.
