Charge Stored in a Capacitor: If capacitance C and voltage V is known then the charge Q can be calculated by: Q = C V. Voltage of the Capacitor: And you can calculate the voltage of the capacitor if the other two quantities (Q & C) are known:. V = Q/C
Initially, a capacitor with capacitance (C_0) when there is air between its plates is charged by a battery to voltage (V_0). When the capacitor is fully charged, the battery is disconnected. A charge (Q_0) then resides on the plates, and the potential difference between the plates is measured to be (V_0). Now, suppose we insert a dielectric that ...

By understanding the principles behind capacitor operation and considering factors such as capacitance value, voltage rating, ripple current, temperature, and form factor, you can confidently select the right capacitor for your applications.
No, you cannot replace a run capacitor with a lower mfd or uf rating. Doing so could damage your appliance or cause it to operate less efficiently. If you install the wrong sized capacitor, the motor will not have an even magnetic field. This can cause the motor to fail. Start capacitors will suffer the same consequences if they are not the ...
