Question

How many 1 μF capacitors must be connected in parallel to store a charge of 1.0 C with a potential of 110 V across the capacitors

Answer 1

Answer:

The stored charge on a capacitor, Q (in Coulombs) can be calculated from the formula:

Q = CV

where C is the capacitance in Farads and V is the voltage. By definition, 1 Farad = 1 Coulomb at 1V on a capacitor.

Assuming your capacitors are rated for 110V or better, one of your microF capacitors can store 1uF * 110V = 1 x 10–6 Coul /Volt * (110 Volt) = .00011 Coulombs of charge at 110V, so you’d need at least 1/.00011 = 9090.9 such capacitors.

Rounding up, about 9091 1uF capacitors would be required at 110V
