Apparatus for Studying f.e.m. and Internal Battery and Battery Resistance
Product Code : SCL-PLE-12372
The Apparatus for Studying f.e.m. and Internal Battery and Battery Resistance (SKU SCL-PLE-12372) is an EMF and internal resistance apparatus for school and college physics. With three 3-4.5 V cells in holders, a digital ammeter, a digital voltmeter, a rheostat and a switch, students measure terminal voltage at different currents and find the EMF and internal resistance of a cell. JaincoLab supplies it for current electricity practicals.
Specifications
The apparatus consists of 3 cells of 3-4.5 V with matching holders, a digital ammeter, a digital voltmeter, a rheostat, six pairs of connecting leads with red and blue connectors and a power switch rated for 36 V and 0-3 A DC.

Applications of the EMF and internal resistance apparatus
The apparatus is used to find the EMF and internal resistance of a cell by recording terminal voltage against current as the rheostat is varied, then reading the EMF from the intercept and the internal resistance from the slope of the graph.
- Determining the EMF of a cell from a voltage-current graph
- Determining the internal resistance of a cell from the slope of the graph
- Comparing the terminal voltage of a cell on open circuit and under load
- Comparing single cells with cells connected in series
- Current electricity practicals in senior secondary and junior college physics
