Transformer Action

Transformer action is a phenomenon by which EMF(Electro-motive force) is induced in from one coil to the other coil by electro magnetic induction. It is the basic principle of electric transformers.

Difference between Higher potential and lower potential

Before getting into the topic, we have to keep two points in mind.1. Conventional Current flow. (The way Current is said to flow historically)
2. ‎Actual current flow. (The way Current actually flows).

Voltage division rule | Potential divider circuit

Voltage division rule

Voltage division rule is one of the basic rules of circuit analysis. It is applicable to all series circuits and combination circuits. Series circuit always acts as a Voltage divider. In a series circuit, the same current flows through each resistance. Hence the voltage drops across each resistor are proportional to their ohmic value.

Current flow in a circuit is determined by the impedance offered by the circuit components, which is in turn determined by the way circuit components are connected. Series connection and parallel connection are the two simplest ways of connecting a circuit.

Ohm’s Law – Relationship between current and voltage

Ohm’s law is one of the basic principles of electricity. It relates the basic parameters of electricity, Current and voltage, to each other. Georg Ohm, after whom the law was named, conduct a few experiments on circuits containing different lengths of wires and found that the voltage applied and current are directly proportional. He derived a complex equation and published it along with his results in the book Die galvanische Kette, mathematisch bearbeitet in 1827.

Conductance | What is conductance?

Conductance is one of the electrical property of a material. It is the reciprocal of resistance. conductance can be defined as the amount of current that a conductor can allow to flow through it.

Inductance | What is inductance? | What is an inductor?

According to Faraday’s law of electromagnetic induction, “Whenever there is a change in current flowing through a coil, a change in magnetic field is produced which induces a voltage across the coil.” A coil is nothing but a twisted wire. When such a coil is formed out of a wire of certain length and cross-sectional area, it acts as an inductor. (more…)
