Resistors
Resistors control the flow of current by offering resistance. They are used to limit current, divide voltage, and set biasing conditions in electronic circuits.
- Resistors oppose the flow of electrical charge or electrical current.
- Resistance is measured in ohm.
- The opposition to the flow of electrical current through the material is known as the resistance of that material.
- Resistors are made up of materials like Tungsten, Bronze, and Constantan.
Resistor voltage equation:
V= I x R
- where V stands for Voltage
- I stands for Current
- R stands for Resistance
Applications of Resistors
- It is used in Potential Divider.
- It helps in Biasing Circuits.
- It is used in Feedback Networks.
- It is used in Amplifiers.
- It is used in Current controlling devices.
- It is used in Coupling Networks.
- It is used in DC Power Supplies.
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.
