The main purpose of a resistor is to maintain specified values of voltage and current in an electronic circuit. A Resistor works on the principle of Ohm's law and the law states that the voltage across the terminals of a resistor is directly proportional to the current flowing through it. The unit of resistance is Ohm.What is the purpose of resistor?
The main function of resistors in a circuit is to control the flow of current to other components. Take an LED (light) for example. If too much current flows through an LED it is destroyed. So a resistor is used to limit the current.What is resistor made up of?

The types of resistors include: Carbon Composition Resistor. Thermistor.What is meant voltage?
Voltage, also called electromotive force, is a quantitative expression of the potential difference in charge between two points in an electrical field. An example of direct voltage is the potential difference between the terminals of an electrochemical cell.Why do we need to use resistors?
Circuits need resistors for, for all manner of reasons. Resistors are used to provide biasing voltages that control the gain of amplifiers, they are used to limit currents to safe levels and prevent overheating, they provide a way to sense current and voltage for circuit control and more.What is meant by resistance?
Resistance is the opposition that a substance offers to the flow of electric current.What is a 100r resistor?
The R is sometimes used as a decimal point. So 100R is 100 Ohms, 4R7 is 4.7 Ohms, etc.How do I calculate resistance?
If you know the total current and the voltage across the whole circuit, you can find the total resistance using Ohm's Law: R = V / I. For example, a parallel circuit has a voltage of 9 volts and total current of 3 amps. The total resistance RT = 9 volts / 3 amps = 3 Ω.What is resistor and its applications?

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.What is the full form of resistance?
Resistance is a measure of the opposition to current flow in an electrical circuit. Resistance is measured in ohms, symbolized by the Greek letter omega (Ω). Ohms are named after Georg Simon Ohm (1784-1854), a German physicist who studied the relationship between voltage, current and resistance.What is the simple definition of resistance?
Resistance is an electrical quantity that measures how the device or material reduces the electric current flow through it. The resistance is measured in units of ohms (Ω). If we make an analogy to water flow in pipes, the resistance is bigger when the pipe is thinner, so the water flow is decreased.What is resistor and its uses?
