Description
● To determine the resistance per cm of a given wire by plotting a graph of potential difference versus current, and hence to determine its resistivity.
● It consists of 2 sets of terminals, one for connecting to an external battery and the other has a resistance across the two terminals.
● When the ON/OFF is pressed, the current flowing in the circuit can be controlled through the variable rheostat knob.
● Circuit is housed in a expoxy metal box with all circuits printed on top.
● Supplied without external battery or resistance.
