When the charge moves in the conductor, it will be collided and rubbed by other particles such as molecules and atoms. The result of collision and friction forms a barrier to the current of the conductor. The most obvious feature of this obstruction is that the conductor consumes electric energy and generates heat (or emits light). ). This hindrance of the object to the current is called the resistance of the object. Resistor is generally called resistance directly in daily life. It is a current-limiting component. After the resistor is connected to the circuit, the resistance of the resistor is fixed. Generally, it is two pins, which can limit the current through the branch connected to it. A resistor cannot be changed and is called a fixed resistor. A variable resistance is called a potentiometer or a variable resistor. The ideal resistor is linear, ie the instantaneous current through the resistor is proportional to the applied instantaneous voltage. Variable resistor for voltage division. On the exposed resistor body, one or two movable metal contacts are pressed. The contact position determines the resistance between either end of the resistor body and the contact.
The terminal voltage and current have a certain functional relationship, and the two-terminal device that converts electrical energy into other forms of capability is represented by the letter R, and the unit is ohm Ω. Actual devices such as bulbs, heating wires, resistors, etc. can be represented as resistor elements.
The resistance value of a resistive element is generally related to temperature, material, length, and cross-sectional area. The physical quantity that measures the magnitude of the resistance affected by temperature is the temperature coefficient, which is defined as the percentage change in resistance value for every 1 °C increase in temperature. The main physical characteristic of a resistor is that it converts electrical energy into thermal energy. It can also be said that it is an energy-consuming component through which current flows to generate internal energy. The resistor usually functions as a partial pressure or a shunt in the circuit. For signals, both AC and DC signals can pass through the resistor.
