Resistors are widely used in electronic equipment. In the circuit, resistors are used to regulate current and voltage and protect electronic components. The power and resistance of the resistor have an important influence on the stability of the circuit. Resistors are used in consumer electronics, communication equipment, medical devices and other fields, among which 1 4w resistor is more common, especially in small electronic equipment and electronic toys.
When choosing a resistor, we need to pay attention to factors such as resistance value, power, accuracy and temperature coefficient. For the resistance of 1 4w, the appropriate resistance value and accuracy should be selected according to the working conditions and requirements of the circuit. If you need to bear a large current or power when working, you should choose a resistor with a large power to ensure the stability of the circuit. At the same time, it is necessary to pay attention to the temperature coefficient of the resistor to ensure that it will not be affected by excessive temperature when working.
