Hint: In an electrical circuit, a capacitor is a component that is used to hold charges. A capacitor operates under the premise that when an earthed conductor is moved close to a conductor, its capacitance increases noticeably. As a result, a capacitor has two plates with equal and opposite charges that are spaced apart.
Complete answer:
The following are some significant justifications for utilising a capacitor in a DC motor:
\[\bullet\] DC motor interference and noise are reduced using capacitors. In addition to reducing magnetic interference, capacitors also lessen motor current peaks.
\[\bullet\] For DC motors that are powered by digital signals, capacitors are utilised.
\[\bullet\] With the frequent fluctuations in motor load, the capacitor helps the motor rotate more smoothly.
\[\bullet\] The capacitor maintains the power circuit functioning properly by absorbing the back emf of the motor.
A capacitor is made up of two parallel plates that are spaced apart by a dielectric. One plate is attached to the positive end and the second plate is connected to the negative end of the capacitor when a DC voltage source is connected across it. Plate I becomes positive with respect to plate II when the potential of the battery is applied across the capacitor.
There is an electric field across the capacitor. From the battery, the positive plate will draw positive charges while the negative plate will draw negative charges. The capacitor can keep the most charge after a particular point due to its capacitance with regard to this voltage. The capacitor's charging time is the duration of this period.
Note: It's crucial that the free electrons on the distant plate don't experience as much of the push from the electrons being added to the negative plate as the plates are separated by more distance. More negative charges cannot be added to the negative plate as a result. The electricity will flow across a short circuit if the plates are closer to one another. This suggests that a parallel plate's capacitance and plate spacing are inversely related.
