Construction of inductor
An inductor is usually constructed as a coil of conducting material, typically opper wire, wrapped around a core either of air or ferrous material.
Core materials with higher permeability than air imprison the magnetic field losely to the inductor, thereby enhancing the inductance. Inductors come in many happens. Most are constructed as enamel coated wire wrapped around a ferrite with wire exposed on the outside, whereas some enclose the wire completely in ferrite and are called shielded'.
The observations from these experiments led to 'The Laws of Electromagnetic Induction' 1) 'If the magnetic flux threading through an electrical circuit changes, then an e.m.f.
The armature of a d.c. machine has a resistance of 0.3 and is connected to a 200V supply. Calculate the e.m.f. generated when it is running (a) as a generator giving 80A (b) as a

Q. Show Common signal-processing operations? Common signal-processing operations include the following: • Amplification to compensate for attenuation • Filtering to reduc
A uniform quantizer is said to have 16 levels, and hence is called a midriser. The saturation levels are to correspond to extreme values of the message of 1 V ≤ f(t) ≤ 17 V. Find
Zener breakdown: Zener Breakdown takes place in very thin junction i.e. when both sides of junction layer is narrow. When a small reverse bias voltage is applied a Very strong
