Resistors in audio

The resistor is a passive electrotechnical component, which has ideally the only property – electrical resistance. It is used to reduce the amount of electrical current or to obtain a certain voltage drop. Fixed resistors have a fixed resistance value that changes only slightly depending on the temperature passing through the current and life of the resistor. Adjustable resistors are used for continuous control (eg volume adjustment) or as temperature sensors (thermistors), voltage (varistors), lights (photoresistors). Continue reading Resistors in audio
