Question

(2:) Q: What can you do to make a parallel-plate capacitor larger? There are several things. Describe as many as you can.

In the RC circuit to the right, the capacitor C has a value of 10 LiF and the resistor is 144 kQ. The battery has an EMF of 16 V.
The circuit is assembled with capacitor is uncharged. At t = 0 s terminal A is cormected to terminal 8, causing the battery to charge the capacitor.

(i) What is the half-life (s) of this circuit? At the time of t = 0.54 s:

(ii) Calculate the voltage of the capacitor.
(iii) Calculate the voltage across the resistor.
(iv) Calculate the current flowing through the circuit. (v) Calculate the power being dissipated in the resistor.

Answer 1

2. We can do to make a parallel-plate capacitor large by following ways

the formula for the capacitance is given as

C = ε(A/d)

• so to increase the capacitor we can increase the area A area of the plates
• we can increase the permitivity of the medium between the plates by inserting the dielectric in between the plates
• by decreasing the distance between the plates d
• by connecting the capacitor in parallel connection in the circuit.

now for the next part ,

capacitor C =10 uF

resistor = 144 kohm

EMF = 16 V
