Abstract: This experiment served to calculate the Ohms by measuring the value of voltage and amperes throughout eight trials. The ohms were calculated using two equations.The first equation was voltage divided by amperes, and the second equation was the rise over run for the slope. The first
equation resulted in R= 2.7175, and the second equation resulted in R= 2.66.
Introduction:
In this lab, we're exploring the basic principles of electrical resistance discovered by Ohm. Ohm found that when voltage changes across a resistor, the current through it changes, too. Ohm's groundbreaking discovery revealed that in a resistor, the current (I) flowing through it is directly proportional to the voltage (V) applied across it, while inversely proportional to the resistance (R), expressed mathematically as I = V/R. By conducting experiments with different resistors, we will investigate the relationship between current and voltage in Ohmic and non-Ohmic materials.
Theory: In this experiment, the constant resistance (Ohms) was calculated by measuring the voltage and amperes throughout eight trials. Ohms was and calculated by this equation: (1) R= V/A. This equation translates to: Ohms is equal to voltage divided by amperes. The equation to find Ohms from slope is:
(2) R= y/x. This translates to Ohms is equal to voltage 1 minus voltage 2, divided by ampere
1 minus ampere 2.
Procedure: Using the diagram of the circuits, the assembly was made. The rheostat was adjusted
to get the current on the voltameter at a minimum and the voltage and current. The rheostat was then adjusted to 50 mA and the voltage along with the current was recorded. Step three was then repeated for a total of eight times to get eight readings. The power supply was then turned off and the circuit disassembled. R x
= V/I was then calculated for each trial (with error estimate) to find the average value of R x for all the trials. With the data gathered from the last step V vs. I was plotted and R x (with an error estimate) was found from the slope of the graph.

Since R1=3198.15ohm, R2=9694.26ohm and Ri=Infinite in the circuit given in the figure, write the equivalent resistance in Ohms between the terminals A-B. When making your transactions, 2 digits will be taken after the dot. Write the result you found according to the margin of error of ± 10% (plus/minus ten percent). While writing the answer, a space is written in front of the value (kOhm, ohm, V, A) etc. values should not be written. Only numeric values should be entered. A period (.) must be used as a decimal separator. Do not use thousands separators (do not use signs such as semicolons). An example notation is given below. Let the value you find be 1.15Kohm. You should write 1150.00 in the box. Let the value you find be 432.63 ohms. You should write 432.63 in the box. If the correct answer is X, values entered in the range of X ± (X*10/100) (including limits) will be accepted. If x=50, it will be accepted as between [45,55].
