    A resistor has multiple bands of color on its side. The most common have four or five but they can range all the way up to 6 per resistor. On a four band resistor, the last band is usually gold or silver. The gold band represents a positive or negative 5% tolerance. The silver band on a resistor represents a positive or negative 10% tolerance.

  4. Photoresistor - Wikipedia › wiki › Photoresistor

    A photoresistor is a passive component that decreases resistance with respect to receiving luminosity on the component's sensitive surface. The resistance of a photoresistor decreases with increase in incident light intensity; in other words, it exhibits photoconductivity. A photoresistor can be applied in light-sensitive detector circuits and light-activated and dark-activated switching circuits acting as a resistance semiconductor. In the dark, a photoresistor can have a resistance as high as

    A potentiometer is a three-terminal resistor with a sliding or rotating contact that forms an adjustable voltage divider. If only two terminals are used, one end and the wiper, it acts as a variable resistor or rheostat.

  6. Thermistor - Wikipedia › wiki › Thermistor

    A thermistor is a type of resistor whose resistance is strongly dependent on temperature, more so than in standard resistors. The word is a combination of thermal and resistor. Thermistors are widely used as inrush current limiters, temperature sensors, self-resetting overcurrent protectors, and self-regulating heating elements. Thermistors are of two opposite fundamental types: With NTC thermistors, resistance decreases as temperature rises usually due to an increase in conduction electrons bum

  7. Varistor - Wikipedia › wiki › Varistor

    A varistor is an electronic component with an electrical resistance that varies with the applied voltage. Also known as a voltage-dependent resistor, it has a nonlinear, non-ohmic current–voltage characteristic that is similar to that of a diode. In contrast to a diode however, it has the same characteristic for both directions of traversing current. Traditionally, varistors were indeed constructed by connecting two rectifiers, such as the copper-oxide or germanium-oxide rectifier in ...

    A resistor is a device that obstructs the flow of current. It a passive two-terminal device which is used to regulate the flow of electric current. Glass, Mica, Wood, Rubber, etc. are examples of resistive materials. The unit of resistance is OHM (Ω) where 1Ω = 1V/1A. In electronic circuits, resistors are used to adjust signal levels, reduce current flow, bias active elements, terminate transmission lines, divide voltages, etc.

    There are numerous types of resistors that are available and can be used in electronic circuits. These different types of resistors have different properties depending upon their manufacture and construction. There are different types of resistors available for various applications. The resistors are available in different shapes, size, and materials. Normally resistors can be classified into two types namely linear resistor and non linear resistor.

    The resistors whose value changes with the applied temperature and voltage, are called as linear resistors. Most types of resistors are linear devices that produce a voltage drop across themselves when a current flows through them There are two basic types of resistors with linear properties namely fixed resistors and variable resistors.

    Non linear resistors are those types of resistors where the electric current flowing through it changes with the exchange in applied voltage or temperature and does not change according to Ohm’s law. There are several types of nonlinear resistors, but the most commonly used are mentioned below.
