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.
IGBT stands for Insulated Gate Bipolar Transistor, a semiconductor device used for switching applications in power electronics.
IGBT is a type of transistor that combines the high efficiency of a bipolar junction transistor (BJT) with the high input impedance of a MOSFET.
It is commonly used in applications such as motor drives, inverters, and power supplies.
IGBTs are used for high power applications due to their ability...

A circuit breaker is an electrical switch that automatically interrupts the flow of current in a circuit in case of an overload or short circuit.
It is a safety device used to protect electrical circuits from damage caused by excess current flow.
It works by detecting the excess current and interrupting the flow of electricity to prevent damage to the circuit.
Circuit breakers are commonly used in homes, buildings, and in...
A relay is an electrically operated switch that uses an electromagnet to mechanically open or close a circuit.
Relays are commonly used in control circuits to switch high voltage or current using a low voltage signal.
They can be used to control motors, lights, and other electrical devices.
Relays can be classified based on their construction, contact configuration, and operating voltage.
Examples of relays include electro...

Relay is an electrically operated switch that opens or closes circuits electronically.
Relays are used to control high voltage circuits with low voltage signals.
They are used in automation systems, power plants, and automobiles.
Examples include electromagnetic relays, solid-state relays, and thermal relays.
A contactor is an electrical device used to control the flow of electricity in a circuit.
Contactor is used to switch on and off electrical power to a load.
It is commonly used in motor control circuits to control the operation of motors.
Contactor helps in protecting electrical circuits from overload or short circuits.
It provides a safe and reliable method of controlling high-power electrical loads.
Contactor can be manua...

The principle of an IC engine involves the conversion of chemical energy into mechanical energy through the process of combustion.
IC engine operates on the principle of internal combustion, where fuel is burned inside the engine to produce power.
The combustion process generates high pressure and temperature gases that expand and push the piston, converting chemical energy into mechanical energy.
The mechanical energy pr...
A diesel engine functions by compressing air in the cylinder, injecting fuel, and igniting the fuel-air mixture to create combustion.
Diesel engines compress air in the cylinder to high pressures, typically around 15:1 compression ratio.
Fuel is injected into the cylinder at the end of the compression stroke.
The fuel is ignited by the heat generated from the high compression, not by a spark plug like in gasoline engines.
...
Diesel is heavier and less volatile than petrol, leading to differences in combustion, efficiency, and emissions.
Diesel is heavier and less volatile than petrol
Diesel engines compress air to ignite fuel, while petrol engines use spark plugs
Diesel engines are more fuel-efficient but produce more emissions
Petrol engines are quieter and faster than diesel engines
Gears are mechanical devices that transmit motion and power between rotating shafts. Types include spur, helical, bevel, worm, rack and pinion.
Spur gears have straight teeth and are the most common type
Helical gears have angled teeth for smoother operation
Bevel gears have cone-shaped teeth for changing direction of rotation
Worm gears have a screw-like appearance and are used for high torque applications
Rack and pinion ...
