Rajputana Stainless Interview Questions, Process, and Tips

A diesel generator works by converting mechanical energy from the diesel engine into electrical energy through an alternator.

• Diesel fuel is injected into the engine where it is compressed and ignited, creating mechanical energy.

• The mechanical energy is then used to turn the alternator, which generates electricity.

• Regular maintenance of the diesel generator is essential to ensure proper functioning and longevity.

• Common ...read more

A block diagram of a transformer shows the primary and secondary windings, core, and connections.

• Primary winding: where the input voltage is applied

• Secondary winding: where the output voltage is obtained

• Core: provides a path for magnetic flux

• Connections: show how the windings are connected

A rectifier is an electrical device that converts alternating current (AC) to direct current (DC).

• Rectifiers are commonly used in power supplies and electronic devices.

• They typically consist of diodes arranged in a specific configuration to allow current flow in only one direction.

• Types of rectifiers include half-wave, full-wave, and bridge rectifiers.

• The output of a rectifier is a pulsating DC voltage, which can be sm

A Thyristor is a four-layer semiconductor device that acts as a switch for high power applications.

• Consists of four layers of alternating N and P type materials

• Has three terminals: Anode, Cathode, and Gate

• Used in applications like motor control, lighting control, and power supplies

Transistors are semiconductor devices that can amplify or switch electronic signals. AC current alternates direction, while DC current flows in one direction.

• Transistors are used in electronic circuits to amplify or switch signals.

• AC current alternates direction periodically, commonly used in household electricity.

• DC current flows in one direction constantly, commonly used in batteries.

• Transistors can be used to amplif...read more
