A capacitor that is connected to a 70.0 V source contains 105.0 µC of charge. What is the capacitor's capacitance?

Capacitance = charge/voltage

C = 105*10^-6 / 70

To find the capacitance of the capacitor, you can use the formula:

C = Q / V,

where C is the capacitance, Q is the charge stored in the capacitor, and V is the voltage across the capacitor.

In this case:

Q = 105.0 µC = 105.0 x 10^-6 C
V = 70.0 V

Now, you can substitute the values into the formula and calculate the capacitance:

C = (105.0 x 10^-6 C) / 70.0 V
C = 1.5 x 10^-6 F

Therefore, the capacitance of the capacitor is 1.5 µF.
