conservation of energy   1. 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.

equilibrium of a particle   3. 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.

newton's 2nd   5. 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.

collision 1D   7. 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.

centripetal force   8. 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.

mechanical equivalent of heat   9. 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.
