Ohm's Law states that V=RI where V is the difference of potential at the poles of the element (measured in volts), R is the resistance of the element being tested (a resistor in this case, measured in ohms), and I is the current passing through the circuit (measured in milliamps). When the Y-intercept on the attached voltage drop vs. current in the conductor graph is examined, it is observed that the the ranges of R values overlap, also the expected y-intercept value of 0 falls between the maximum and minimum deviation. By further examining the graph,it is possible to notice that the plot of the voltage drop across the conductor versus the current in the conductor results in a straight line. Furthermore, the origin (0,0) is within experimental error for the y-intercept of the graph. Both these statements show that the tested resistor verified Ohm's Law since theoretically the y-intercept should be 0 and the voltage drop across the conductor versus the current in the conductor should be directy proportional. This can be concluded by observing the equation which is y = .054492x ± 0.0016x -.0254 ± 0.10.

This laboratory had few causes of error that could significantly affect results. The most important factor was a mildly fluctuating power supply (the indicated current did not remain perfectly stable after being adjusted). Another possible cause of error is the possibility of misreading the voltage drop because of the fluctuating power supply. A miscalibrated multimeter could potentially result in inaccurate readings as well since the voltage drop readings were made directly without recalibrating it against a calibrated machine.

...Voltage: Ohm'sLaw and Kirchhoff's Rules
ABSTRACT
Ohm'sLaw and Kirchhoff's rules is fundamental for the understanding of
dc circuit. This experiment proves and show how these rules can be applied to
so simple dc circuits.
INTRODUCTION
In the theory of Ohm'sLaw, voltage is simply proportional to current as
illustrated in the proportionality, V=RI. As shown in this relation, V
represent voltage which is...

...JOULE’S LAW
Introduction and research question
In this experiment, we were going to investigate the resistance R of an immersion heater. We had to make our own heater, and measure the resistance using a multimeter. Then we had to measure the current I, using an ammeter and a voltmeter. And at last, we had to determine the power P of the immersion heater. This experiment would require to make a table with the data collection, a graph, and a few calculations using Joule’s and...

...OHM’SLAW
AIM OF THE EXPERIMENT
Confirmation of OHM’SLAW
THEORY:
It was George Simon Ohm (1787-1854) who established experimentally that the current in a metal wire is directly proportional to the potential difference V applied to its two ends, provided that the physical conditions such as temperature remain constant:
I∞V
Exactly how much current flows in a wire depends not only on the voltage, but also on the...

...OHM’SLAW
INTRODUCTION
Ohm'slaw states that the current through a conductor between two points is directly proportional to the potential difference or voltage across the two points, and inversely proportional to the resistance between them provided the temperature remains constant.
The mathematical equation that describes this relationship is:
where V is the potential difference measured across the resistance in units of volts; I is...
