Chapter 21, Problem 1RQ
Can current flow through a capacitor?
Expert Solution & Answer
To determine
Whether the current can flow through capacitor.
Answer to Problem 1RQ
No, current cannot flow through a capacitor.
Explanation of Solution
Description:
Construction wise, a capacitor is composed of two metal plates separated by an insulating material called dielectric. As there is no closed path available between the plates, the current cannot pass through a capacitor when at rest. However, when a capacitor is being charged or discharged, it gives a closed path, thus allowing current to pass through it.
To summarize, current cannot flow through a capacitor. However it allows current to pass through during the time when it is being charged or discharged.
