Explain Magnetostriction.
Magnetostriction: If ferromagnetic materials are magnetized a small change of dimensions of the material obtains place. There is a small extension along with equivalent reduction of cross-section of the crystals of that the material is made. When this rapidly alternating magnetic fields so there is a rapid and continuous extension and contraction of the material. It is termed as magnetostriction. This magnetostriction is the main cause of hum in transformers and chokes.
Q. For the circuit given in Figure, develop and execute a PSpice program to solve for the node voltages.
Electrical energy If the power is measured in watts and the time in seconds then the unit of energy is watt- seconds or Joules.
