Question

A 5 μF capacitor is connected to a 12 V battery. The charge on each plate of the capacitor is:

Select one:
a. 6 x 10-5 C
b. 6 x 105 C
c. 6 x 10-6 C
d. 60 C

Answer 1

1 farad = 1 coulomb/volt

5 μF = 5 x 10⁻⁶ coulomb/volt

= 60 x 10⁻⁶ coulomb / 12 volts

The charge is 60 x 10⁻⁶ coulombs = 6 x 10⁻⁵ (choice-A)
