Crossover Resistors for sale

A resistor is a passive electrical two-terminal crossover component that, as a circuit part, implements electrical resistance. Resistors are used in electronic circuits, among other uses, to adjust signal levels, to reduce current flow, to divide voltages and to terminate transmission lines. Here at SoundImports, you can buy fixed resistors from quality brands such as Dayton Audio, Jantzen Audio, Monacor and Mundorf!

What is the function of a resistor?

Resistors are used in a variety of applications. A resistor is an electrical component that creates resistance in the flow of current. They can be found in almost all electrical networks placed on printed circuit boards and electronic circuits. Resistance is calculated in ohms. The voltage across the terminal ends determines the current. Ohm's rule describes this ratio.

What is the difference between resistor and resistance?

Resistors are electrical components with a fixed resistance, such as 1 ohm, 10 ohms or 100 ohms. When a potential difference is applied through a conductor, the amount of current that passes through it is called resistance.

What is the difference between a fixed and a variable resistor?

The difference between fixed and variable resistors is that resistors are fixed only slightly with temperature, time, or operating voltage. In comparison, it is possible to use variable resistors to change circuit components, such as volume control. However, we at SoundImports only offer fixed resistors.

What is the difference between a wire-wound resistor and a metal oxide resistor?

Wirewound resistors are typically created around a ceramic, plastic, or fibreglass core by winding a metal wire, usually nichrome. Two caps or rings fixed to the core's ends are soldered or welded to the wire ends. There are wire-wound resistors with high and low energy. A ceramic outer case or an aluminium outer case on top of an isolating sheet is used with higher power wire-wound resistors. Such resistors are often referred to as "cement" resistors if the outer case is ceramic, though they do not contain any conventional cement. On the other hand, metal oxide film resistors are made of metal oxides, contributing to a higher working temperature and better stability and durability.
