Why do weaker capacitors have the the largest voltage acros
The strength of a capacitor, or its capacitance, is a determining factor in the voltage across it. A stronger capacitor can store more charge, so when the same amount of charge is applied, the voltage across it will be lower. Similarly, a weaker capacitor has lower capacitance and therefore a higher voltage across it when the same amount of ...
