Magneti Marelli Motherson Auto System Interview Questions, Process, and Tips

Capacitor stores energy in an electric field, while a battery stores energy in a chemical form.

• Capacitors store energy in an electric field, while batteries store energy in a chemical form.

• Capacitors can discharge their energy quickly, while batteries discharge their energy slowly.

• Capacitors are used for short-term energy storage, while batteries are used for long-term energy storage.

• Capacitors are commonly used in ele...read more

A diode is an electronic component that allows current to flow in only one direction.

• It has two terminals, an anode and a cathode.

• It is commonly used in rectifiers, voltage regulators, and signal limiters.

• It can be made of various materials such as silicon, germanium, or selenium.

• It has a forward voltage drop that varies depending on the material and current flow.

• It can be used to convert AC to DC in power supplies.

Voltmeter measures potential difference in parallel and ammeter measures current in series due to their internal resistance.

• Voltmeter has high internal resistance and measures potential difference across two points in parallel

• Ammeter has low internal resistance and measures current flowing through a circuit in series

• Connecting voltmeter in series would cause a voltage drop and affect the accuracy of measurement

• Connecti...read more

Photodiode is a semiconductor device that converts light into electrical current.

• Photodiode operates in reverse bias mode

• It is used in light detection and optical communication systems

• It has high sensitivity and fast response time

• Examples include PIN photodiode and avalanche photodiode

2 stroke engines have a power stroke in every revolution while 4 stroke engines have a power stroke in every other revolution.

• 2 stroke engines have a simpler design and are lighter than 4 stroke engines.

• 4 stroke engines are more fuel-efficient and produce less pollution than 2 stroke engines.

• 2 stroke engines require a mixture of oil and fuel while 4 stroke engines have separate oil and fuel systems.

• In a 2 stroke engine...read more
