## Circuit Elements

Circuit Elements: Let us take a brief review of three basic Circuit Elements namely resistance, capacitance and inductance. Resistance It is the property of the material by which it opposes the flow of current through it. The resistance of element is denoted by the symbol ‘R’. Resistance is measured in ohms (Ω). The relation between […]

## Definition of Inductance

Definition of Inductance: Definition of Inductance – Voltage induced in a circuit is given by where ψ represents the flux linkages of the circuit in weber-turns (Wb-T). This can be written in the form where L=dψ/di is defined as the inductance of the circuit in henrys, which in di general may be a function of […]

## Magnetically Induced Emf and Force

Magnetically Induced Emf and Force: Magnetically Induced Emf and Force – Faraday’s law of induction, which is the integral form of the fourth Maxwell’s equation, is given as The integrated form of Eq.(2.15) for a coil of N turns is The positive direction of current in the coil is that direction which establishes positive flux […]
