Experiment No.1

Here I have to obtain 6 resistors of different colours and calculate and measure the values using colour coding and Ohmmeter.

Now I have to choose two individual resistors and record there ohm resistance value measured by the ohmmeter.

Resistor 1 = 0.22M Ohms

Resistor 2 = 0.33K Ohms

Now I have to calculate and measure both the resistors in series.

Calculated Value 1 and 2 in series

0.22M ohms + 0.33K ohms = 0.55M ohms

Measured Value 1 and 2 in series

0.55M ohms

Now I have to calculate and measure both the resistors in parrallel.

Calculated value 1 and 2 in parallel

Rt = R1 X R2/R1 + R2 = 0.45 X 0.13/0.45 + 0.13 = 0.0585/0.58 = 0.10K ohms

Measured Value 1 and 2 in parallel

0.13K ohms

What principles of electricity have you demonstrated with this? Explain:

After carrying out the calculations i get to know that the resistance are to be added togerther in the series whereas in parallel the resistance is low than the individual resistance.
