Explanation:
Experiment : To check the impact of material, cross section area and length of resistor on resistance
Items required; Vernier caliper, multi meter, different sample, cm ruler, battery source and connecting wires
Procedure;
To conduct the experiment, take different samples and note their parameters such as material type, cross section via Vernier calliper and length via cm ruler. Now connect each sample with a known battery source and complete the circuit with the sample resistance. Measure the current in each and then determine the resistance of each sample using ohm’s law
