Explain Resistor

November 30, 2019

A resistor is an electrical component that limits or regulates the flow of electrical current in an electronic circuit. As explained above the fourth stripe is the measure of tolerance of the resistor which means how much does the resistance change under varying operational conditions such as temperature etc.

Tell Me What Is A Resistor

Resistor color code chart.

Explain resistor. The chart below shows how to determine the resistance and tolerance for resistors. The tolerance of a resistor is the maximum difference between its actual value and the required value and is generally expressed as a plus or minus percentage value. The resistance is measured in ohms.

These resistors are generally of low values so that the over all performance of the circuit is not affected. 10000 ohms or 10 k ohms plus the last line shows the tolerance of the resistor. In electronic circuits resistors are used to reduce current flow adjust signal levels to divide voltages bias active elements and terminate transmission lines among other uses.

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. The resistor is a passive electrical component to create resistance in the flow of electric current. A resistor is a passive circuit element which decreases the current flow andor drops the voltage on purpose.

A resistor is a passive two terminal electrical component that implements electrical resistance as a circuit element. Fixed and variable resistors. 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. The table can also be used to specify the color of the bands when the values are known. There are two common types of resistor.

A resistor when introduced in series with the supply terminals of the circuit helps in checking the sudden rise in voltage and averting a possible harm. Resistors can also be used to provide a specific voltage for an active device such as a transistor. 1kw or 1000w 20 1200w.

For example a 1kw 20 tolerance resistor may have a maximum and minimum resistive value of. Tips for reading resistor codes. In almost all electrical networks and electronic circuits they can be found.

An automatic resistor calculator can be used to quickly find the resistor values. A resistor is a little package of resistance.
