Rheostat Manufacturer,Supplier and Exporter in India
Product Code : EL-PL-13423
Jlab Export is a leading Rheostat Manufacturer,and suppliers in India
Rheostat (code EL-PL-13423) is a 5 Ω variable resistor rated at 3 A, with a copper-graphite sliding contact, for controlling the current in a circuit by changing the resistance in it. In practicals it sets the brightness of a lamp or the speed of a small motor. Model JL345 is one of the resistors JLab manufactures for physics laboratories in Ambala, India.

Where a 5 Ω Rheostat Makes a Difference
Connected in series, the rheostat adds anything from almost nothing to its full 5 Ω, depending on where the sliding contact rests on the winding. That span has a large effect in low-resistance circuits such as a torch lamp or a small DC motor, where a few ohms change the current noticeably. In a circuit of several hundred ohms the same 5 Ω would hardly alter the current, so a higher-value rheostat suits that work.
Working Within the 3 A Rating
Set the contact so the whole winding is in circuit, close the switch, then slide towards lower resistance while watching an ammeter. Heat in the winding rises with the square of the current, so stay below 3 A and open the circuit between readings. The ±10% tolerance on the 5 Ω value is another reason to read the current from a meter rather than work it out from the nominal resistance.
