Question: If the voltage across a capacitor in an AC circuit is 100V and the capacitive reactance is 50Ω, what is the current through the capacitor? (2023)

Options:

Correct Answer: 2A

Exam Year: 2023

Solution:

Current (I) = Voltage (V) / Capacitive Reactance (XC) = 100V / 50Ω = 2A.

If the voltage across a capacitor in an AC circuit is 100V and the capacitive reactance is 50Ω, what is the current through the capacitor? (2023)

Step 1: Identify the voltage across the capacitor. In this case, it is 100V.
Step 2: Identify the capacitive reactance (XC) of the capacitor. Here, it is 50Ω.
Step 3: Use the formula for current (I) in an AC circuit with a capacitor: I = V / XC.
Step 4: Substitute the values into the formula: I = 100V / 50Ω.
Step 5: Calculate the current: 100 divided by 50 equals 2.
Step 6: Conclude that the current through the capacitor is 2A.
