Expert Solution

A transformer is a static device which transfers electrical energy from one circuit to another through the process of electromagnetic induction. It is most commonly used to increase (‘step up’) or decrease (‘step down’) voltage levels between circuits.

The working principle of a transformer is very simple. Mutual induction between two or more windings (also known as coils) allows for electrical energy to be transferred between circuits.

An electric motor is an electrical machine that converts electrical energy into mechanical energy. Most electric motors operate through the interaction between the motor's magnetic field and electric current in a wire winding to generate force in the form of torque applied on the motor's shaft.

Generator is a machine that converts mechanical energy into electrical energy. It works based on principle of faraday law of electromagnetic induction. ... So the important elements of a generator are: Magnetic field.

A major application of ferro- and ferrimagnetic materials is in transformer and motor cores. Materials are required that are magnetically soft (high permeabilities – they are magnetized easily at low applied fields and a low coercive field) with large power-handling capacity and low losses. Why cannot pure iron metal be used in transformer cores? Account for the magnetic behavior of the following spinels: (a) ZnFe2O4 is antiferromagnetic (b) MgFe2O4 is ferrimagnetic and its magnetic moment increases with temperature c) MnFe2O4...

The terminal voltage across a single phase of a stepper motor used as a generator is applied across a load resistor of 33 ohms. This terminal voltage has an amplitude of 18.7V and a frequency of 242 Hz. From a previous measurement, we know that this stepper motor phase has an internal resistance of 11.2 ohms. What is the time-averaged power delivered to the load? What is the electrical efficiency of this circuit? Write down an expression for the instantaneous...
