Inductors
Inductors store and release magnetic energy. They are used for applications such as filtering, energy storage, and impedance matching.
- All inductors are coiled structures and insulated wire wrapped around the area.
- Inductors work on electromagnetic induction.
- It is used to decrease the electric spikes in electronic circuits.
Inductor Current equation with respect to time:
[Tex]V(t) = L\frac{di(t)}{dt} [/Tex]
- V(t) stand for voltage across the inductor with respect to time t
- L stands for inductance
- i(t) stand for current through the inductor with respect to time t
Applications of Inductors
- It is used in minimizing alternating current in the circuits.
- It is used in RF choke in the oscillator.
- It is used in LC resonance.
- It is used in Radio Transmitter and receiver.
Passive Components in Electrical Circuits
In electronic components, Passive components are electronic devices that don’t need an external power source to operate actively. They do not generate power rather they store and release it. They mainly resist, store, or control the flow of electric current or voltage in a circuit without actively amplifying or generating signals. Passive components include resistors, capacitors, inductors, diodes, and coils – that don’t require power to do their job.
A circuit is an interconnection of elements. Based on their capability to generate energy these elements are classified into active or passive elements. Electric circuits are made up of three circuit components. These are resistance, inductance, and capacitance. These are called passive circuit elements and they do not transfer electrical energy. Passive elements stores energy in the form of voltage or current.
