Q
Q: If the voltage across a capacitor in an AC circuit is 100 V and the capacitive reactance is 50 ohms, what is the current through the capacitor? (2021)
Solution: Current I = V/Xc = 100 V / 50 ohms = 2 A.
Steps: 5
Step 1: Identify the voltage across the capacitor, which is given as 100 V.
Step 2: Identify the capacitive reactance, which is given as 50 ohms.
Step 3: Use the formula for current in an AC circuit with a capacitor: I = V / Xc.
Step 4: Substitute the values into the formula: I = 100 V / 50 ohms.
