The following figures represent the symbol of a. These resistors consist of a fixed resistor element and a slider which taps onto the main resistor element.

Fixed resistor connections. Fixed resistors are one type of linear resistors. Two connected to the fixed element and the third is the slider. A rheostat is a variable resistor which is used to control current.

A variable resistor potentiometer or pot as it is more commonly called is a good example of a multi resistor voltage divider within a single package as it can be thought of as thousands of mini resistors in series. In case of variable resistors we use a single resistor for different resistance values. The cost of fixed resistors is high when compared to the cost of variable resistors because each time to change the resistance we need to buy a new fixed resistor.

Resistors can be seen in almost all electronic circuits. Here a fixed voltage is applied across the two outer fixed connections and the variable output voltage is taken from the wiper. The most used symbol is the international iec resistor symbol displayed on the left but the american resistor symbol displayed on the right is also still used.

A resistor is said to be a fixed resistor if its value is fixed. The main function of the resistor is to resist the flow of electric current and regulate the flow of electrons. This gives three connections to the component.

Symbol of fixed resistor. Fixed and variable wire wound resistors fixed wire wound resistors are used in audio frequency dc and ac circuits as voltage dividers as well as damping and terminating resistors for establishing. Potentiometers can be used as rheostats using two connections in stead of three.

In this way the component acts as a variable potential divider if all three connections are used. A resistor when connected in a circuit that connection can be either series or parallel. The following resistor symbols are often used to depict resistors with a fixed value.

There are many types of resistors and they can be divided into two groups namely fixed resistor and adjustable resistor variable resistor. The resistance of the fixed resistor is measured by using the ammeter. Let us now know what will happen to the total current voltage and resistance values if they are connected in series as well when connected in parallel.

The value of fixed resistor cant be varied like a variable resistor as its value is determined at the time of manufacturing itself. Let us observe what happens when few resistors are.
