Resistance Substitution Box

Resistance Substitution Box is a convenient instrument for determining the desired resistance values in circuits under design or test. This resistance substitution box has 12 different values 100 Ω, 220 Ω, 470 Ω, 1 kΩ, 2 kΩ, 4kΩ, 10 kΩ, 22 kΩ, 47 kΩ, 100 kΩ, 220 kΩ and 470 kΩ . All resistors are precision 1% resistors and are of 1-watt rating. Selected resistor can be attached in any circuit with 4mm two red safety sockets.
