Answer
Vc = 22V, the potential difference between the capacitor
Explanation
Let
ε = 32 V
R = 5k ohms
C = 30uF
I = 2mA
Required
Vc= ? Potential difference between the capacitor
Solution
Vc = ε - I*R
= 32V - (2mA*5000 ohms)
= 32V - 10V
Vc = 22V , the potential difference between the capacitor
The capacitance given will be used in finding the charge between the capacitor, Q ;
Q = Vc*C
