A useful apparatus capable to verify Ohm's Law & unknown resistance.
Instrument consists of two moving coil meters of range 5V & 100mA to measure voltage & current, One wire wound potentiometer, Circuit diagram printed on front pannel, two 4mm socket terminals are provided for the connection of unknown resistance & another two terminals for D.C. input. Provided with built-in DC regulated power supply or without power supply all components enclosed in the cabinet. Supplied with four different carbon resistances. To verify Ohm's Law & hence find the unknown resistance.
