Capacitors typically look like this. We have an electrolytic and a ceramic type capacitor. The electrolytic is polarised meaning one side must be connected to the positive and one to the negative of the power supply. The ceramic type can generally be connected either way. On the side of the electrolytic capacitor, we.

Calculation: f = 1 / (2 π * 100 Ω * 1 x 10-6 F) f ≈ 1591.55 Hz. Therefore the frequency at which the 1uF capacitor may have a reactance of 100 Ω is approximately is 1591.55 Hz. Alternatively, by knowing the applied frequency and the reactance value of the capacitor at that frequency, we may calculate the capacitor''s Farad value.

Capacitance can be calculated when charge Q & voltage V of the capacitor are known: C = Q/V. If capacitance C and voltage V is known then the charge Q can be calculated by: Q = C V. And you can calculate the voltage of the capacitor
If a potential difference is maintained across the two plates of a capacitor (for example, by connecting the plates across the poles of a battery) a charge +Q will be stored on one plate and Q on the other. The ratio of the charge stored on the plates to the potential difference V across them is called the capacitance C of the capacitor. Thus:

The amount of charge stored in a capacitor is calculated using the formula Charge = capacitance (in Farads) multiplied by the voltage. So, for this 12V 100uF microfarad capacitor, we convert the microfarads to Farads (100/1,000,000=0.0001F) Then multiple this by 12V to see it stores a charge of 0.0012 Coulombs.
