Chapter 23: Problem 7

A capacitor is said to carry a charge \(Q .\) What's the net charge on the entire capacitor?

Short Answer

Expert verified
The net charge on the entire capacitor is 0.

Step by step solution

01

Understand the capacitor structure

A capacitor is a two-terminal electrical device that can store energy in an electric field. It consists of two conducting plates separated by an insulator or a vacuum. When a voltage is applied across the terminals, an electric field is created between the two plates, storing energy.
02

Understand charge distribution

Whenever a capacitor is said to carry a charge \(Q\), it generally means one plate carries a charge of \(Q\) and the other carries a charge of \(-Q\). This happens because of charge conservation principle. According to this law, charge can neither be created nor destroyed but can be transferred from one body to another.
03

Determine the net charge

As explained in step 2, one plate of the capacitor carries a positive charge \(Q\) and the other carries an equal negative charge \(-Q\). Adding these two gives us the net charge on the entire capacitor, which is \(Q + (-Q) = 0\).
