Why resistor is used in circuits. Mostly resistors are used to set up different voltages level in circuit and to limit current. By adding a resistor in series you can increase the natural resistance. Resistor is used in every electronic and integrated circuit.

It is a passive element means it consume power. By adding a resistor in parallel you can decrease the natural resistance. The resistor is a component that resists current.

The role of the resistor in an electrical circuit. A resistor is a two terminal electronic component that produces a voltage across its terminals that is proportional to the electric current through it in accordance with ohms law. It is one of the most basic of electrical components.

In electronic circuit its resistance is used to limit current or for better understanding it limits flow of electron. If you add a resistor in series with a circuit the current in the circuit will be lower than without the resistor. Diagrams links and practice questions in this document are still to be added.

An important function is when a resistor is used as a heating element as in the case of irons toasters heaters electric stoves and hair dryers. Resistor is a passive component that is used in almost all the circuit boards in electronics. In a typical application a resistor is connected in series with an led makes enough current flows to make the led light up but not so much that the led is damaged.

Variable ones may function as sensors switches or voltage dividers. A resistor is used to limit the current in a circuit further answer a resistor is sometimes used to modify the natural resistance of a circuit eg. In direct current dc or alternating current ac electrical circuits that have a resistor as its name implies resists the flow of electrons.

The purpose of resistor is to exhibit resistance to the current flowing through it and thereby got the name resistor you must have guessed it by now. Resistors also produce light as filaments in light bulbs.

Transistor Power Amplifier

We will discuss the need for proper biasing in the next chapter. This type of biasing arrangement uses two resistors as a potential divider network across the supply with their center point supplying the required base bias voltage to the transistor.

Transformer Coupling Model

This application note covers the following topics explaining the use of inductor coupling symbols in a capture pspice project. This transformer wont work properly because ltspice does not know this is a transformer. The Effects Of Mutual Coupling And Transformer Connection Aaronscher Com Resonant Coupling Networks Figure 6 From High Efficiency Magnetic Coupling Resonant Barrere exality corporation a transformer with individual winding inductances l1 and l2 has mutual inductance m between the windings. Transformer coupling model . In practice some flux traverses paths that take it outside the windings. Such flux is termed leakage flux and results in leakage inductance in series with the mutually coupled transformer windings. The last number is called mutual coupling coefficient and can be between 0 and 1. However if you are only interested in a...
