A diode is an electronic component that allows current to flow in one direction and blocks it in the opposite direction.
Diodes are made of semiconductor materials, such as silicon or germanium.
They have two terminals: an anode (positive terminal) and a cathode (negative terminal).
When a diode is forward-biased, it allows current to flow through it.
When a diode is reverse-biased, it blocks the current.
Diodes are commonl...
A diode is a two-terminal electronic component that allows current to flow in one direction and blocks it in the opposite direction.
A diode has an anode and a cathode terminal.
It is represented by a triangle with a line at the base.
The arrowhead of the triangle points towards the cathode terminal.
The line at the base represents the anode terminal.
The symbol of a diode is often accompanied by its part number or label.
Conductor, insulator, and semiconductor are materials with different electrical conductivity properties.
Conductor: Materials that allow the flow of electric current easily. Examples: copper, aluminum.
Insulator: Materials that do not allow the flow of electric current. Examples: rubber, glass.
Semiconductor: Materials with intermediate conductivity. Examples: silicon, germanium.

I applied via Recruitment Consultant and was interviewed before Oct 2017. There were 3 interview rounds.
The basic hydraulic system consists of various valves and pumps that work together to control fluid flow and pressure.
Valves in a hydraulic system control the direction, flow rate, and pressure of the fluid.
Examples of valves include check valves, relief valves, and control valves.
Pumps in a hydraulic system generate the flow and pressure of the fluid.
Examples of pumps include gear pumps, vane pumps, and piston pumps.

The speed difference in a hydraulic ram is due to the difference in effective areas on the head side and rod side.
The head side of the ram has a larger effective area, resulting in slower speed.
The rod side of the ram has a smaller effective area, resulting in faster speed.
This speed difference is a result of the hydraulic pressure acting on different areas.
The speed ratio between the head side and rod side can be calc...
A pressure relief valve is used to protect equipment and systems from excessive pressure by releasing the pressure when it exceeds a certain limit.
Prevents damage to equipment and systems
Ensures safety of personnel
Maintains system integrity
Prevents explosions or ruptures
Relieves excess pressure by opening and releasing fluid or gas
Commonly used in boilers, pressure vessels, pipelines, and hydraulic systems
An orifice is a small opening or hole through which fluid or gas can flow.
Orifices are commonly used in various industries, such as plumbing, engineering, and manufacturing.
They are often used to control the flow rate of fluids or gases.
Orifices can be found in devices like nozzles, valves, and flow meters.
The size of an orifice determines the flow rate and pressure drop across it.
Examples of orifices include the tiny ...

Open loop and closed loop are two modes of operation in hydraulic systems.
Open loop operation: The hydraulic system operates without feedback control. The output is not adjusted based on the system's performance.
Closed loop operation: The hydraulic system uses feedback control to adjust the output based on the system's performance.
Open loop systems are simpler and less expensive, but they lack precision and accuracy.

The starting circuit is responsible for initiating the engine's operation.
The starting circuit consists of components such as the battery, starter motor, ignition switch, and solenoid.
When the ignition switch is turned on, it sends a signal to the solenoid, which then engages the starter motor.
The starter motor uses electrical energy from the battery to turn the engine's crankshaft, starting the combustion process.
