Charged plates voltage

WebSince capacitance is defined to be charge over voltage, we can rewrite this as charge equals capacitance times voltage. If we substitute the capacitance times voltage in for the charge, we see that the energy of a capacitor can also be written as 1/2 times the capacitance times the voltage across the capacitor squared. But now we have a problem. WebAt some point, the existing negative charge on the first plate will be so repulsive that it prevents you from adding any more negative charges to that plate. In this case the capacitor is fully charged. This maximum charge Q Q Q Q corresponds to the final voltage of the charged capacitor in the relation Q = C ⋅ V Q= C \cdot V Q = C ⋅ V Q ...
