Resistors are common elements of electrical networks and electronic circuits and are ubiquitous in electronic equipment. Practical resistors as discrete components can be composed of various compounds and forms. Resistors are also implemented within integrated circuits. A single in line (SIL) resistor package with 8 individual 47 ohm resistors.
Resistors (and other elements with resistance) oppose the flow of electric current; therefore, electrical energy is required to push current through the resistance. This electrical energy is dissipated, heating the resistor in the process.
A resistor limits the electric current that flows through a circuit. Resistance is the restriction of current. [ 1 ] In a resistor the energy of the electrons that pass through the resistor are changed to heat and/or light.
A photoresistor (also known as a light-dependent resistor, LDR, or photo-conductive cell) is a passive component that decreases in resistance as a result of increasing luminosity (light) on its sensitive surface, in other words, it exhibits photoconductivity.
Understanding the differences between available resistor types and how to select the right one. First we will discuss the familiar “discrete” or axial-lead type resistors we are used to working with in the lab; then we will compare cost and performance tradeoffs of the discrete versions and thin- or thick-film networks. Axial Lead Types:
In electronic logic circuits, a pull-up resistor (PU) or pull-down resistor (PD) is a resistor used to ensure a known state for a signal. [1] It is typically used in combination with components such as switches and transistors, which physically interrupt the connection of subsequent components to ground or to V CC.
