In the sliding resistor, there is a current limit element. Essence Come to study and study the comparison of the comparison of the comparison of the middle use, and the fixed value is also used as a variable resistance. To change the length of the medium metal in the circuit circuit circuit circuit circuit, the length of the circuit circuit is related.
Precautions for sliding resistors
1. The connection should be used;
2. Before, to be adjusted to the most;
3. To slide the specific specifications, not only in line, the current is in line, and the current meets the compliance.
Slide variants application
1. The principle of measuring the blocking box is
2. Daily: The resistance values ??in electric iron and electric iron circuits such as table lamps and lights, etc.
Slide the resistor function
1. Through the part of the part, the current, thereby changing the connection with it
2, the circuit, that is, good, electric key, should be adjusted before, should be adjusted
