Apti,core subject in engineering
DOL (Direct-On-Line) and star delta are two different wiring schemes used in electrical engineering for starting induction motors.
DOL wiring directly connects the motor to the power supply for starting, while star delta wiring initially starts the motor in star configuration and then switches to delta configuration for running.
DOL wiring is simpler and cheaper but causes high starting current, while star delta wiring r...

Hard work versus smart work.
The power plug earth wire is bigger in size to ensure safety and prevent electrical shocks.
The earth wire provides a path for the current to flow in case of a fault or short circuit.
A larger wire size reduces resistance and allows for the safe dissipation of excess current.
It helps to protect individuals and equipment from electric shock hazards.
The earth wire is connected to the ground, which acts as a reference point...
Copper (Cu) conductor will take larger current than Aluminum (Al) conductor of the same size.
Copper has a higher electrical conductivity than Aluminum.
Copper has a lower resistivity than Aluminum.
Copper has better thermal conductivity than Aluminum.
Copper is more commonly used in high-current applications.
Aluminum is often used in overhead power transmission lines due to its lighter weight.
Pulse width modulation (PWM) is a technique used in VFD to control the speed of the motor by adjusting the width of the pulses of voltage supplied to the motor.
PWM is a method of controlling the amount of power delivered to a load without changing the voltage level.
In VFD, PWM is used to control the speed of the motor by varying the width of the pulses of voltage supplied to the motor.
The width of the pulses is control...
