Resistors Exp.1

Experiment 1. Determining resistance..

Objective.

Had to obtain 6 different resistors of different resistant values and calculate the value of each resistor by using a colour code chart using the maximum and minimum tolerance of each resistor, then measure each resistor value with our multimeters.

Results to experiment..

I then chose 2 resistors and then recorded there individual ohm resistances which i measured with my multi meter.

Resistor 1.. 990 ohm's

Resistor 2.. 2117 ohm's

Then we were required to connect the 2 resistors in series (joint end on end) and had to calculate the value in series (3107 ohm's) and then the actual test reading through a multimeter (3166 ohm's)

Next we had to connect them in parallel (both ends when they are side to side, end joint to end, almost joint like a circle) the calculated value was (3107 ohm's) and then again the measured recording through a multimeter was (.679 ohm's)

This experiment showed that the resistance when tested in series was added together to give you a joint resistance, where as when you test them in parallel you divide up the resistance because there is now 2 paths for the electricity to flow.
