DC circuit refers to an electric circuit where the current flows in one direction only.

• DC stands for direct current, which means the flow of electric charge is uni-directional.

• DC circuits are commonly used in electronics, batteries, and power supplies.

• Examples of DC devices include flashlights, cell phones, and solar panels.

Self motor is not a commonly used term in electrical engineering.

• It is possible that the interviewer meant to ask about self-starting motors, which are motors that can start without external assistance.

• Another possibility is that they were referring to self-excited motors, which generate their own magnetic field without the need for a separate excitation source.

• It is important to clarify the question with the interview

Alternators are electrical generators that convert mechanical energy into electrical energy.

• Alternators are commonly used in vehicles to charge the battery and power the electrical system.

• They work by using a rotating magnetic field to induce an electrical current in a stationary coil of wire.

• Alternators are more efficient and reliable than traditional generators.

• They are also smaller and lighter, making them ideal for...read more

Batteries are devices that store chemical energy and convert it into electrical energy.

• Batteries come in various sizes and types, including alkaline, lithium-ion, and lead-acid.

• They are commonly used in electronic devices, vehicles, and backup power systems.

• Batteries have a positive and negative terminal, and the flow of electrons between them creates an electrical current.

• The capacity of a battery is measured in amper
