When a length of wire is formed into a coil, as shown in Figure 1, it becomes a basic inductor. The terms coil and inductor are used interchangeably. Read more about INDUCTOR

There are three main series of transistor codes used in the UK:The first letter B is for silicon, A is for germanium (rarely used now). The second letter indicates the type; for example C means low power audio frequency; D means high power audio frequency; F means low power high frequency. Read more about Transistor codes

Resistance Conductance and Ohm's Law. It is the property of a material due to which it opposes the flow of electric current. "R" represents it. It, s unit is called ohm.

A transformer is an electrical device used to change the  value of an alternating voltage. transformers are widely used in electrical  work. Read more about TRANSFORMER

Opposition to the flow of current is called resistance and the device or component used for this purpose is called resistor. Read more about Resistor

Any linear bilateral circuit, which contain, G/R of same frequency the current that flows in any branch is the sum of the current's that would result from each G/R Working independently while other G/R.

Ohm's law states that in an electric circuit the current is directly proportional to the applied voltage and inversely proportional to the resistance of the circuit.

First Law of Faraday's Electromagnetic Induction state that whenever a conductor are placed in a varying magnetic field emf are induced which is called induced emf, if the conductor circuit are closed current are also induced which is called induced current.

In Figure we can now look at the circuit from the example, redrawn with the calculated voltage and current values included. Read more about TRANSFORMER CHARACTERISTICS

Resistance Test on a Transformer Connect an ohmmeter across the two ends of the primary winding of the transformer and record the resistance. Read more about TRANSFORMER RESISTANCE TEST
