Chapter 19: Q48PE (page 698)

What charge is stored in the capacitor in Example 19.8?

Short Answer

Expert verified

The amount of charge stored in a capacitor when 3.00脳103V is applied to it, is Q=26.6渭颁 .

Step by step solution

01

Given data

Area of plates (A) = 1.00 m2

Separation between plates (d) = 1.00 mm

Voltage between the plates (V) = 3.00 x 103V

02

Concept Introduction

The ability of any capacitor to store energy in the form of electric field is known as Capacitance. The capacitanceC is given as 鈥�

C=Q螖痴.....................(1)

Here Q is the charge accumulated at the plates and 鈭�Vis the potential difference between the plates.

03

Calculation for Charge Stored

The charge stored in the capacitor is found by solving Equation (1) for Q 鈥�

Q=C脳螖痴

Entering the values for C and 鈭�V, it is obtained 鈥�

Q=(8.85脳10-9F)(3.00脳103V)=26.6脳10-6C=(26.6脳10-6C)(106渭颁1C)=26.6渭颁

Therefore, the charge stored is Q=26.6渭颁.
