Ramsey electrical components Germany Ramsey model Ramsey price

Ramsey electrical components are current-limiting components. After connecting a resistor in a circuit, the resistance value is fixed, typically with two pins, and it can limit the magnitude of the current flowing through the branch to which it is connected. Resistors whose resistance cannot be changed are called fixed resistors. Those with variable resistance are called potentiometers or variable resistors. An ideal resistor is linear, meaning the instantaneous current through the resistor is proportional to the applied instantaneous voltage. Variable resistors used for voltage division. One or two movable metal contacts are pressed tightly against the exposed resistive body. The contact position determines the resistance between either end of the resistive body and the contact.
