Voltmeter Manufacturer,Supplier and Exporter in India
Product Code : EL-PL-12423
Jlab Export is a leading Voltmeter Manufacturer,and suppliers in India
Voltmeter (code EL-PL-12423) is a DC voltmeter with a 0–15 V range, model JL369/083, for measuring the potential difference between two points of a circuit in school, college and university laboratories. The range covers circuits run from a few cells or a low-voltage DC supply. JLab makes it in Ambala, India, alongside the ammeter and milliammeter of the same series.

Connecting It Across, Not in Line
A voltmeter goes in parallel with the part being measured, one lead to each end of the resistor, lamp or cell. Join its positive terminal to the side nearer the positive pole of the supply, otherwise it reads the wrong way. Its high resistance means very little current is diverted through it, so the circuit behaves almost as before. That same high resistance is why it must never be placed in series: it would cut the current to almost nothing.
Using the 0–15 V Range in an Ohm’s Law Run
With the voltmeter across a resistor and an ammeter in series, a rheostat raises the current a step at a time and each pair of readings is noted. A straight line through the origin on a graph of V against I shows Ohm’s law, and its slope gives the resistance, R = V/I. Keep the supply below 15 V so the reading stays on scale; if the voltage is unknown, begin with the rheostat at its maximum resistance and work upward.
