Capacitor block AC and allows DC to pass through.
A
true
B
false
C
not ascertain
D
it purely depends on the value of capacitor
Explanation
Explanation:
- Capacitors do not allow DC to pass through because, in a DC circuit, the capacitor charges up to the supply voltage and then acts as an open circuit, blocking any further current flow.
- However, capacitors allow AC to pass through because the constantly changing voltage in an AC circuit causes the capacitor to charge and discharge, thus allowing current to flow.
Key Points:
- Capacitors block DC.
- Capacitors allow AC to pass by offering a certain reactance depending on the frequency of the AC signal.
Correct Answer: B) false
