Steel Strips Wheels Interview Questions, Process, and Tips

A transformer is an electrical device that transfers electrical energy between two or more circuits through electromagnetic induction.

• Transformers are used to increase or decrease voltage levels in electrical circuits.

• They consist of two coils of wire, known as the primary and secondary coils.

• The primary coil is connected to the input voltage source, while the secondary coil is connected to the output load.

• Transformers...read more

A relay is an electrically operated switch that controls the flow of electricity in a circuit.

• Relays are used to control high power circuits with low power signals.

• They consist of a coil and one or more sets of contacts.

• Relays can be used for various applications such as controlling motors, lights, and appliances.

• Common types of relays include electromagnetic relays, solid-state relays, and reed relays.

A motor is a device that converts electrical energy into mechanical energy to produce motion.

• Motors can be found in various applications such as electric vehicles, industrial machinery, and household appliances.

• There are different types of motors including DC motors, AC motors, and stepper motors.

• Motors consist of a rotor and a stator, with the rotor rotating inside the stator to generate motion.

• Examples of motors incl...read more

Four-stroke and two-stroke engines differ in their operating cycles and efficiency.

• Four-stroke engines have separate intake, compression, power, and exhaust strokes, while two-stroke engines combine these strokes.

• Four-stroke engines are more fuel-efficient and produce less pollution compared to two-stroke engines.

• Two-stroke engines have a simpler design and are lighter, making them suitable for applications where weigh...read more

Bearings are used to reduce friction and support rotating or moving parts in machinery.

• There are several types of bearings, including ball bearings, roller bearings, and plain bearings.

• Ball bearings use balls to reduce friction between the moving parts.

• Roller bearings use cylindrical rollers to support heavy loads.

• Plain bearings have a sliding surface and are used in applications where low friction is required.

• Other ty...read more
