Ohms Law Apparatus Manufacturer,Supplier and Exporter in India
Product Code : ILS-LM-10824
Indian Lab Suppliers supplies the Ohms Law Apparatus (Product ID: 10824) as part of its lab meters range. This boxed apparatus lets students vary the voltage across a resistor and verify Ohm's law.
Quick Answer
A spray-painted metal box carries two moving-coil meters, a 5 V voltmeter and a 500 mA milliammeter, with a wire-wound potentiometer to vary the voltage. There are 4 mm sockets for the DC supply and for the unknown resistance, an ON/OFF switch, and the circuit diagram printed on the front panel. Plotting V against I gives a straight line whose slope is the resistance. Supply options of 1.5 V, 3 V and 4.5 V are listed with a step-down transformer and leads; since moving-coil meters need DC, please confirm the supply arrangement at quotation.
