What is the capacitance of an element if it takes 1 minute t

What is the capacitance of an element if it takes 1 minute to charge from 0 V to 6 V using a steady current of 1.5 mA?

Select one:
a. 1.5 uF
b. 6 mF
c. 15 mF
d. 10 pF

Solution

The leakage current through a capacitor is the ratio rate of change of voltage across capacitor to the rate of change of time multiplied by that capacitor value.

i.e. Ic = C(dV/dt)

C = Ic/(dV/dt)

C = 1.5mA/((6-0)V/(60-0)S)

C = 15 mF
