Electric Motor:
A device, which converts electric energy into mechanical energy is known as Electric Motor.
Factors on which the speed of Rotation of Motor Depends:
The speed of rotation of motor depends on the following factors.
1. Magnitude of current passing by the motor.
2. Strength of magnetic field.
3. Number of turns in the coil of the motor.
4. Permeability of its armature.
a. Consider an x-ray machine with a step-up transformer consisting of a primary coil of 100 turns and a secondary one with 50000 turns. If the voltage applied across the primary co
Deduce the expression for expected fringe shift in Michelson Morley experiment. Discuss the result of experiment.
These resistors are usually of carbon composition, carbon film on a ceramic rod and sealed in evacuated glass tube. End connections are made up of copper clad nickel-iron alloy.
