Chapter 25: Q2P (page 739)

The capacitor in Fig. 25-25 has a capacitance of $25 μF$ and is initially uncharged. The battery provides a potential difference of 120 VAfter switchis closed, how much charge will pass through it?

Short Answer

Expert verified

Charge passing through the battery is $q = 3.0 \times 10^{- 3} C$

Step by step solution

Given

The capacitance of the capacitor is $C = 25 μF (\frac{10^{- 6} F}{1 μF}) = 2.5 \times 10^{5} F$ .

The potential difference is V = 120 V.

Determining the concept

Using equation 25-1, find the amount of charge that passes through the battery.

Formulae are as follows:

$C = \frac{q}{V}$

Where C is capacitance, V is the potential difference, and q is the charge on the particle.

(a) Determining the charge passing through the battery

From equation 25-1 we know that,

q = CV

The charge passing through the battery is,

$q = (2.5 \times 10^{- 5} F) (120 V) = 3.0 \times 10^{- 3} C$

Hence, the charge passing through the battery is $3.0 \times 10^{- 3} C$

Therefore, by using the formula for capacitance find the charge passing through the battery.
