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.
D Flip Flop As we have seen in the SR flip flop when the inputs S= R are applied the forbidden or indeterminate state occurs. This state can destabilize the SR file flop.
Q. For the circuit shown in Figure(a), determine the diode current and voltage and the power delivered by the voltage source. The diode characteristic is given in Figure.
