Re: What are Potentiometers?
so many things - like "a volume control acts as a filter" - thats not correct
back before voltage and current were defined by agreed to names (voltage was named after Voltaire) a device for measuring voltage was referred to as a potentiometer (potential meter) but that terminology is now obsolete.
A potentiometer is a variable resistor, nothing more. Its not a voltage source, its not a current source, its not a measuring device.
If you dont know what a pot is, the Wiki entry is very misleading and confusing.
