What is the Resistance Decade Box?
Sun, Jan 19, 2020
The resistance decade box is an electromagnetic relay that can adjust the resistor and display the resistance size of the resistor. If it is compared with the slide rheostat, the slide rheostat cannot express the resistance value of the connected power circuit, but it can continuously change the resistor in the connected power circuit. The resistance box can express the size of the resistance in the power circuit, but the resistance transition is not continuous. The role of the resistance box is that the resistance value of the circuit can be arbitrarily changed, thereby changing the current and voltage of the circuit.
