What''s the Difference Between Capacitors and Batteries?

In the field of electronics, there are two methods in which energy can be stored: batteries and capacitors. While batteries are familiar to most of us, not many people are aware of the role that capacitors play in standard electric circuits.

What is the effect of adding a capacitor and a battery in parallel?

Hence, we put capacitors in parallel to act as temporary sources of energy that the battery cannot provide. If the battery load took 100 mA pulses for a millisecond (now and then) and, we wanted the capacitor to not drop anything more than 0.3 volts (for example), we would need a capacitance of: -
