20.5: Modeling circuits with capacitors

So far, we have modeled circuits where the current does not change with time. When a capacitor is included in a circuit, the current will change with time, as the capacitor charges or discharges. The circuit shown in Figure (PageIndex{1}) shows an ideal battery 1 ((Delta V)), in series with a resistor ((R)), a capacitor ((C), two vertical bars) and a …

Capacitor vs. Battery: What''s the Difference?

We don''t use capacitors as batteries because they can''t store as much energy as batteries, and they also can only handle current in one direction. Additionally, capacitors are usually much smaller in size and weight than batteries, which means they are not suitable for applications that require a lot of energy or that need to be charged or …
