A substitution unit that uses a single rotary switch to select from 12 values of resistors. Values are 100, 330, 470. 680, 1 k, 3.3 k, 4.7 k, 6.8 k, 10 k, 33 k, 47 k and 100 k.
The connection to other apparatus is via 4 mm sockets and standard patch leads.
A quick, easy way of using known values of resistors in practical work. No more lost components, misread codes, just turn the switch to the value required and use.
Ideal companion to the Capacitor investigation (charge and discharge) apparatus.
