Electric Field Mapping Using several boards with different conducting patterns and a voltmeter, students trace equipotential lines.               Download:Electric Field Mapping.pdf 2. Coulomb Balance The force of attraction between two plates of a capacitor will be related to the voltage applied by first using a weight and measuring the movement of the plates under the force of gravity, and then removing the weight and applying a voltage to achieve the same movement.           Download:Coulomb Balance.pdf 3. Voltage, Current, and Resistance The purpose of this experiment is to learn how voltage and currents are generated and measured in the laboratory, and to investigate how voltage and current are related in resistors.             Download: Voltage, Current, and Resistance.pdf 4. Oscilloscope In this lab, the students become familiar with 2 oscilloscopes, the model 2120B made by BK Precision, and the Capstone scope.             Download: Oscilloscope.pdf 5. Charge to mass ratio of Electron In this experiment e/m of the electron is determined from the relationship between the electric potential used to accelerate the electron to a given speed, the strength of the magnetic field that influences the electron's motion, and the radius of the circular path which the electron follows.           Download: Charge to mass ratio of Electron.pdf 6. Current Balance In this experiment, the students verify that the force between two wires are proportional to the product of the currents, and estimate the proportionality constant involved.             Download: Current Balance.pdf 7. Electromagnetic Induction In this experiment an emf will be induced in one coil by moving a magnet near the coil, moving a second coil with a current in it near the first coil, and by changing the current in the second coil.             Download: Electromagnetic Induction.pdf 8. RC Circuit This lab is concerned with the characteristics of capacitors and circuits with resistors and capacitors connected in series (RC circuits). The primary focus will be on the response of a RC Circuit to a step voltage and a voltage square wave.             Download: RC Circuit.pdf 9. RLC Resonance In this lab, students use a cirucit with a resistor (R) an inductor (L) and a capacitor (C) connected in series to explore the characteristics of an oscillating system. When the system is driven at its natural frequency, the phenomenon of resonance occurs. Students will measure the natural frequency of the system and observe the time dependent voltages across each of the components.       Download: RLC Resonance.pdf
