Resistors (resistors) are commonly and directly referred to as resistances in daily life. Is a current limiting element, and after a resistor is connected in a circuit, the resistance value of the resistor is fixed, generally two pins, and the resistor can limit the current passing through a branch connected with the resistor. The resistance value that cannot be changed is called a fixed resistor. Variable resistance is called a potentiometer or a variable resistor. Ideally the resistor is linear, i.e. the instantaneous current through the resistor is proportional to the applied instantaneous voltage. A variable resistor for voltage division. On the exposed resistor body, one to two movable metal contacts are pressed. The contact location determines the resistance between either end of the resistor and the contact.
