The maximum voltage of transmission line in India is 765 kV.
The highest voltage level in India is 765 kV.
This voltage level is used for long distance transmission of electricity.
India has several high voltage transmission lines, including the Raigarh-Pugalur HVDC line.
The maximum voltage level has increased over the years, from 400 kV to 765 kV.
Higher voltage levels allow for more efficient transmission of electricity.
Various methods like V/F control, rotor resistance control, and vector control are used for speed control of induction motors.
V/F control method varies the frequency and voltage supplied to the motor to control its speed.
Rotor resistance control method involves inserting external resistance in the rotor circuit to control the speed.
Vector control method uses advanced algorithms to control the speed and torque of the mo...

Logical Questions
An engine is a machine that converts fuel into mechanical energy to produce power.
An engine typically consists of cylinders, pistons, valves, and a crankshaft.
Engines can be classified into different types such as internal combustion engines, steam engines, and electric motors.
Examples of engines include gasoline engines in cars, diesel engines in trucks, and jet engines in airplanes.
A clutch is a mechanical device used to connect and disconnect the power transmission between two rotating shafts.
Clutches are commonly used in vehicles to engage and disengage the engine from the transmission to change gears.
There are different types of clutches such as friction clutches, hydraulic clutches, and electromagnetic clutches.
Clutches can be operated manually by the driver or automatically by the vehicle's ...
2 stroke engines have power strokes every revolution, while 4 stroke engines have power strokes every other revolution.
2 stroke engines have a simpler design with fewer moving parts compared to 4 stroke engines.
2 stroke engines require a fuel-oil mixture for lubrication, while 4 stroke engines have a separate oil reservoir.
2 stroke engines produce more pollution due to incomplete combustion, while 4 stroke engines are ...
Petrol engines use spark ignition, while diesel engines use compression ignition.
Petrol engines use a spark plug to ignite the fuel-air mixture, while diesel engines rely on compression to ignite the fuel.
Petrol engines are lighter and more responsive, while diesel engines are more fuel efficient and have higher torque.
Petrol engines are typically used in cars and motorcycles, while diesel engines are commonly found in
