Question

Problem 93

Answer 1

Given information

Given circuit diagram:

and are two capacitor

is the voltage of the power source

To determine the charge on each capacitor after switching, We are going to use the following formula

Where,

          is the charge in the capacitor

          is the capacitance

          is the potential difference across the capacitor

Step-by-step explanation

Step 1.

Condition

When the switch is down the total charge stored by the capacitor is given as

                                           ....(a)

Condition

When the switch is turned upward then the capacitors   and  make the parallel connection, and in parallel connection, the voltage remains the same. As this is an ideal case, that is why we are going to assume there is no loss.

 

The equivalent capacitance is of the circuit is calculated as
