suggest an experiment to compare the conductivity of electricity by iron ,copper,aluminium and zinc .Perform the experiment and prepare a s
hort report on the results
Answers
Answer:
AIM :-
To compare the electrical conductivity of different metals.
APPARATUS :-
cell, torch bulb fitted in a holder,connecting wires, different metal strips.
PROCEDURE :-
1. Let us make a simple circuit by connecting one end of the torch to cell and other end end of torch to metal strip and to cell back .
2. Let us insert a piece of Aluminium foil between the wires .And we will observe.
3. Repeat the same activity with different metal strips like Iron, copper and Zinc .
OBSERVATION :-
1. In case of aluminium,iron,copper and zinc we observe that , bulb glows in the circuit.
2. This experiment proves that all metals are good conductors of electricity.
3. Copper wire is the best conductor among all the metals.
CONCLUSION :-
This experiment proves that all metals are good conductors of electricity and
Copper wire is the best conductor among all the metals.
