Find the value of a capacitor with voltage 5V and 30C.
A
7f
B
6f
C
15f
D
0.17f
Verified Correct Answer: B.
Physical Principles & Numerical Solution
The capacitance of a capacitor is given by: C = \(\frac{Q}{V}\)
where Q = quantity of charges, and V = voltage
Q = 30c and V = 5v
C = \(\frac{Q}{V}\) = C = \(\frac{30}{5}\) = 6 farad
