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: -

Capacitors Basics

When capacitors are connected in parallel, their total capacitance increases. This means that the combined capacitors can store more electrical charge . Connecting capacitors in parallel is like expanding the storage capacity by adding more tanks to hold the charge since the equivalent capacitance is the sum of individual …
