Resistance variable called potentiometer or variable resistor

Resistor (Resistor) in everyday life generally referred to simply as resistors. A current limiting element, the resistance circuit breakers to the circuit, the resistor value is fixed and is usually two pins, which limits the current through it even slip size. Can not change the resistance called a fixed resistor. electric transformer called potentiometer or variable resistor. Ideal resistor is linear, that is the instantaneous current through the resistor is proportional to the instantaneous voltage applied. For a mcb circuit breaker divider. The exposed resistance of the body, pressed against the metal contacts can be moved one or two. Contact either end position determining resistor and the resistance between the contacts.
