Group Names: Hisham Sageer
Objectives:
Our object is to confirm Ohm’s law by analyzing the dependence of the electrical current as a function of voltage and as a function of resistance. Also, we studied the current flow and voltage in series and parallel. Finally, the lab determined the equivalence resistance of series and parallel combination of resistors and compared the results with theoretical data.
Theoretical Background:
The first thing that needs to be described in this lab is what the electric current I:
I =. The electric current is defined as charge …show more content…
2 Investigate the variation of the current with resistance when the voltage is constant. a Use the same circuit setup and set the output voltage of power supply to 12V. b By keeping the output voltage of the power supply constant, vary the resistance of the resistor box from 700 Ω to 1700 Ω in increments of 200 Ω. Record values of the current I through the resistor and the corresponding resistance R in table2.
Data:
Attached to report.
Calculations:
1 Use the data from table 1 to plot a graph of current Vs. voltage for both values of the resistance. Determine the slope of the graph. From the slope of the graph find the resistance using:
a) R = R = R =1000 Ω
% diff = = 0%
b) R = R = R =1250 Ω
c) Slope = 12.7
V = 12 v
Questions:
1. Does your resistance follow Ohm’s law? Base your answer on your

3601 Words  15 PagesABSTRACT: The lab of one dimensional motion is a series of experiments that deal with different types of motion in a single direction. In the first experiment, one dimensional motion of a small cart on an air track is measured in a one photogate system. The acceleration was calculated by the infrared light emitting electrode of the photogate sensing the slacks on the picket fence. The calculation for gravity yielded 9.63 m/s^2, which is consistent with the accepted value of 9.8m/s^2. In the…

Introduction The amount of heat required to raise the temperature of a solid body depends on its change in temperature (ΔT), its mass (m), and an intrinsic characteristic of the material forming the body called specific heat (cp). The heat is calculated from the equation II. Purpose The purpose of this laboratory is to determine…

1031 Words  5 PagesChemistry Honors Lab 1: Measurements Theory The overall objective of this lab experiment is to learn about measurements. Most to all experiments and labs require some form of measurements. Because there are many various kinds of measurements, it is important to be aware of the different factors of each measurement involved with the current lab experiment. It is also important to have a general understanding of them because they will need to be used in calculations for the lab. Precision and accuracy…

1053 Words  5 PagesThermodynamics Lab Purpose: The purpose of this lab is to determine the identity of an unknown metal, and to prove whether the laws of thermodynamics hold when determining this identity. Using the accepted specific heat of water (4186 J/kg · oC), heat flow between two different sets of water though the conduction of an unknown metal can provide useful data in determining the identity. The heat transfers can be calculated to approximate the specific heat of the unknown metal. When heat is transferred…

It is the force that causes things to happen as they do, such as an apple falling from a tree, or allowing movement in the human body(Energy What Is It?, 1994). Energy is a very general term, and can therefore be sorted into many branches of fields; such as chemical energy, nuclear energy, or solar energy. However…

Objectives The objective of this lab is to create an RC circuit that has a time constant of 10. 2. Method and Principle: The RC circuit that we created on the breadboard was a series circuit. RC circuits contain resistors and capacitors, and are connected to a voltage source. In our case, this voltage source was the battery. When we were measuring the voltage on the computer, we used a switch instead…

We used Ohm’s law R=V/I and R=E/I and the values of current and voltage to find the resistance of an electric circuit. We also found that the SI unit of volt are Joules/Coulomb and that power is measured in Watts. Questions and Answers 1. State the equation…
