(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.

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

2. You are an engineer trying to design a capacitor. You have a
parallel-plate capacitor made of two circular metal plates. The
radius of each plate is 1 m and they are separated by a distance of
0.1 mm. If the space in between the plates was filled with vacuum,
the capacitor would have a capacitance of 0.278 μF but you want to
make this capacitor have a capacitance of 1.0 μF. You only have
paraffin (K=2.2) and glass (K=5)...
