Background

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. The terminal voltage and the current have a determined functional relation, and a two-terminal device which reflects the capability of converting electric energy into other forms is represented by a letter R and has the unit of ohm omega. Actual devices such as bulbs, heating wires, resistors, etc. may be represented as resistor elements. The magnitude of the resistance of a resistive element is generally related to temperature, material, length, and also cross-sectional area, and the physical quantity that measures the magnitude of the resistance affected by temperature is the temperature coefficient, which is defined as the percentage of the change in resistance value for each 1 c increase in temperature. The main physical characteristic of the resistor is that the electric energy is changed into heat energy, and the resistor can also be called as an energy consumption element, and the electric current generates internal energy through the energy consumption element. The resistor generally plays a role in voltage division and shunt in the circuit. For signals, both ac and dc signals may pass through resistors.
