PHY 114 Lab Report 4: Physics of a Light Bulb. Arizona State University.ABSTRACT: The objective of this lab was to understand and be able to compare the relation between voltage and current in a small flashlight bulb and to verify the Stefan Boltzmann law of radiation. By using a circuity involving a DMM, a DC power supply, a light bulb, and a computer interface with voltage sensors, several plots were made to help determine specific values in the circuit. An internal resistance of 2.67 Ohms ...

PHY 114 Lab Report 5: DC Circuits: Electric Power. Arizona State University.ABSTRACT: The goal of this lab was to use a DC circuity with varying internal resistances to figure out find the optimal load resistance that would have the best power output. A circuit was set to test this, and 2 separate tests were made. One tested where the internal resistance is gradually increased to match the load resistance, the other has a set intermediate resistance. The efficiency of the set ups are 91.587% ...

PHY 114 Lab Report 7: Current Balance. Arizona State University.ABSTRACT: The goal of this lab was to prove the definition of an ampere by studying small forces between two parallel current carrying conductors. The conductors were set at equilibrium and contact positions and several measurements were taken to help calculate the distance between the conductors. Thus value allowed the calculation of the theoretical slope of the experiment. Gradually increasing masses were put on the set up, th...

PHY 114 Lab Report 8: Faraday’s Law of Induction. Arizona State University.ABSTRACT: The goal of this lab was to verify Faraday’s law of induction by studying the small electromagnetic force generated between a small coil and comparing it to its theoretical output. At 40 Hz the magnetic field the magnetic field B was calculated at 28.45 and the theoretical was calculated to be 29.3. This is an error of about 2.9%. Overall the lab was successfully completed.

PHY 114 Lab Report 9: Reflection and Refraction of Light . Arizona State University. ABSTRACT: The goal of this experiment was to verify Snell’s law and the law of reflection. By shining a laser through solid plastic and water, it became possible to study these these properties of light by measuring their angles of incidence, their critical angles and their angles of refractions. The slopes of i vs. θr and sin θ1 vs. sin θ2 for each medium made it possible to confirm Snell’s law, and...

PHY 114 Lab Report 3: Capacitors and Electrostatics. Arizona State University. ABSTRACT: The main objective of this lab was to study and capacitors to help measure the electrostatic force between two objects. This was done by using several capacitors 0.1 F, 1.0 µF, and an unknown. They were used to collect data on how energy was transferred and the total amount of energy transferred. The capacitors all gave an output of 0.47 V, 0.89 V, and 1.78 V respectively. Graph plotted in part D showed ...

PHY 114 Lab Report 2: Electric Field Plotting . Arizona State University.ABSTRACT: The purpose of this experiment was to find and understand electric field and equipotential lines, and the relationship between them in two different conductive fields. These fields were presented as parallel lines as an equivalent to parallel plate capacitor and two concentric circles as an equivalent to coaxial cylinders. This electric field between two parallel conductors was found to follow the equation of E...

PHY 114 Lab Report 1: Absorption of Nuclear Radiation. Arizona State University.ABSTRACT: The purpose of this experiment was to find the attenuation factor for beta radiation ( τ ). By placing different radiative sources into a Geiger-Mueller counter, it became possible to measure these intensities and plot them in a graph and find the slope of the trends. This slope was used to find τ which was 0.173. Compared to the expected theoretical value of 0.20 g/cm there was a percent error of ...
