Fixed resistors have resistances that only change slightly with temperature time or operating voltage.

What is the job of a fixed resistor. Variable resistors can be used to adjust circuit elements such as a volume control or a lamp dimmer or as sensing devices for heat light humidity force or chemical activity. Various types of fixed resistors are used in circuits they are the most numerous of all electronic components and their most common job is to reduce voltages and currents around a circuit so that active components transistors and integrated circuits for example that carry out tasks such as. The fixed resistors are classified into different types depending upon their manufacturing processes and the materials used in their manufacturing.

Various types of fixed resistors are used in circuits they are the most numerous of all electronic components and their most common job is to reduce voltages and currents around a circuit so that active components transistors and integrated circuits for example that carry out tasks such as producing or amplifying signals within the circuit are supplied with the correct voltages and currents to work properly. The resistor is a passive electrical component to create resistance in the flow of electric current. To increase the amount of resistance the number of loops in the spiral can be increased.

They can do that by adding tiny components called resistors. The core of the resistor is made of a helix or spiral of conductive material wrapped around an insulating core. An ohm is the resistance that occurs when a current of one ampere passes through a resistor with a one volt drop across its terminals.

Wire it into a circuit and you reduce the current by a precise amount. The resistor is a component that resists current. The initial switch on of a power supply may at times inflict a dangerous voltage surge into an electronic circuit damaging its critical components.

But what about the resistor. The job of the resistor is to control the amount of electricity that flows through the circuit. The material is very very thin which forces the current to slow down to pass through providing resistance.

A resistor is a little package of resistance. The value of fixed resistor cant be varied like a variable resistor as its value is determined at the time of manufacturing itself. People who make electric or electronic circuits to do particular jobs often need to introduce precise amounts of resistance.

The following figures represent the symbol of a fixed resistor. A resistor is effectively used to control this charging and discharging process and its value is varied to obtain different time intervals. In almost all electrical networks and electronic circuits they can be found.

A resistor is said to be a fixed resistor if its value is fixed. If you add a resistor in series with a circuit the current in the circuit will be lower than without the resistor.
