ou can see in the picture is the internal physical diagram of the cell. It contains a resistor and the cells voltage. Resistor that is connected here is not seen as this is not connected in the cell or it is outside the cell. It is the resistor that is of the cell. And emf of the cell is constant means that the emf of the particular cell does not change.

Ohms law:  At constant temperature, voltage is directly proposal to the product of the current flowing and the net resistance.

V=IR

The electrochemical series

Finding the emf the cell is like this:

EMF = Positive charge giving compound  is subtracted by the negative charge giving compound.

Positive charge giving compound I use is carbon. Which has E= 0.13

negetive charge giving compound I use is zinc. Which has E= -0.76

EMF = 0.13-(-0.76)

=0.13+0.76

=0.89V

Requirements for experiment: 1

Any metals like (aluminum foil), connecting wire, multimeter, alligator clip, cotton.

Procedure for experiment: 1
1.Take any alluminium foil present at your home.
2. Take anything that absorbs water in it and place in top of it. Not very much little bit only.

3. Add water in it so that paper becomes wet.

4.Connect multimeter into it positive wire or red wire upon the paper and negative wire or black wire on the alluminium foil.

Note: Never ever try to meet the aluminium foil to the positive or red wire of multimeter nor negative or black wire in water.

5. This is the small battery you can see in front of you can also make it. In your home if you want more current replace paper with charcoal. And add lemon in the water or vinegar. If you connect battery in series then you will get more voltage.
