What Is An Example Of A Resistor

The principal job of a resistor within an electrical or electronic circuit is to resist hence the name resistor regulate or to set the flow of electrons current through them by using the type of conductive material from which they are composed. Ohms law states that the voltage v across a resistor is proportional to the current i where the constant of proportionality is the resistance r.

But what about the resistor.

What is an example of a resistor. Here are examples of resistors. Resistors are carefully manufactured to provide a predetermined value of electrical resistance which may range from 01 ohms to 100000000 ohms. The resistor is the most common electronic component and is used to limit andor control the voltage and current in an electronic circuit.

The resistor is a component that resists current. Filament in a bulb. Resistors are used for many purposes.

They are commercially available with resistance values over a range of more than nine orders of magnitude. A device that has electrical resistance and that is used in an electric circuit for protection operation or current control. Resistors can also be used to provide a specific voltage for an active device such as a transistor.

From the outside all resistors look more or less the same. Wire it into a circuit and you reduce the current by a precise amount. A resistor is an electrical component that limits or regulates the flow of electrical current in an electronic circuit.

A few examples include delimit electric current voltage division heat generation matching and loading circuits control gain and fix time constants. Download basic electronic components pdf a mini ebook with examples that will teach you how the basic components of electronics work. Resistors can also be connected together in various series and parallel combinations to form resistor networks which can act as voltage droppers voltage dividers or current limiters within a circuit.

For example if a 300 ohm resistor is attached across the terminals of a 12 volt battery then a current of 12 300 004 amperes flows through that resistor. A resistor is a little package of resistance. As you can see in the top photo on this page a resistor is a short worm like component with colored stripes on the side.

What is an example of a resistor. Resistance reduces the flow of current in a conductor. If you add a resistor in series with a circuit the current in the circuit will be lower than without the resistor.
