Question 98Electricity & Electronics - 1st Asst/Chief
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, which states that the current (I) is equal to the voltage (V) divided by the impedance (Z). In this case, the voltage is 120 volts and the impedance is 200 ohms. Plugging these values into the formula, we get: I = V / Z I = 120 volts / 200 ohms I = 0.60 amperes The other answer choices are incorrect because: A) 0.01 amperes is too low. C) 1.67 amperes is too high. D) 100 amperes is significantly too high.
