Calculate the capacitance of a system that stores 9.4 x 10-10 C of charge at Q
50.0 V. Use C=
AV
O A. 1.9 x 10-11 F
OB. 4.7 x 10-8 F
O C. 5.3 x 1010 F
O D. 2.1 x 107 F

A. .

Explanation:

By definition of Electric Capacitance, the capacitance of the system (), in farads, is described by the following formula:

(1)

Where:

- Electric charge, in coulombs.

- Voltage, in volts.

If we know that and , then the capacitance of the system is:

The correct answer is A.

a

explanation:

no diagram was provided, but i'm guessing it's the one i've attached to my answer.

here, a mechanical force turns the rod.   this generates an electric current in the coil, which powers the bulb.

increase masses, decrease separation
