PHYS 2020-003: Principles of Physics II

• Hi Al, I only want your leaf electroscope. I will bring my own stuff to class, Starts at at 2:00 PM Richard

• 2 x 4 and watch glass

• Two parallel plates.charge them up with 90 volts battery,measure voltage across the plates. disconnect batteries. show voltage is still there. two metal spherical conductors as usual, one odd shaped conductor. I bring my own charging kit

• Use the small Van de Graaff generator instead of the big one Thanks Richard

•  video  - Van de Graaff Generator

• Hi Al Same as last time Small VDG, screen for my arm, metal pointer, stool Thanks again

•  video  - Parallel Plate Capacitor
•  video  - Capacitor Discharge

• Hi Al, 1) I would like a broken 100 Watt light bulb or something similar to see the filament and measure its resistance. 2) I would like to discharge a small capacitor through an LED to show how the light decays. Thanks Richard

• 3D sticks showing right hand rule and magnetic force law two red and blue bar magnets, some compasses

•  video  - Magnetic Deflection of an Electron Beam

• Midterm Exam 1 - no demos

• Hi AL, 3D sticks to show RHR for Lorentz force

  Magnets, power supply, cathode ray tube to show bending of electron beam. Same as your previous set up 1 week ago.

• Magnet collection

• Also include the 3 batteries strong magnetic, and wire to show how the wire will jump when the current flows. The same setup as you had last time Thanks again

• 1x 2x 4x Coils and Bar Magnet
•  video  - Hanging Ring and Magnet
• Flash Bulb Coil
•  video  - Lenz's Law and Eddy Currents

• I would like a thick copper bar like the one you use for slowing down the magnetic pendulum. I have my own magnet. I will also show a phet video on back emf.

•  video  - Transformers
  ( I do not need Jacob's ladder. I only want the transformer and lightbulbs.)

•  video  - Hanging Ring and Magnet
•  video  - Lenz's Law and Eddy Currents

•  video  - Series LCR Circuit, Resonance
  ( Hi Al, Series RL circuit as you set it up. Resistors 10 Ohms, Lightbulb, and 110 Ohms Inductor 4.2 mH f =300 Hz to show difference in phases f=1 Hz to show lightbulb flicker Max voltage 4.0 volts iron bar to move inside inductor to show effect Thanks Richard )

•  video  - Series LCR Circuit, Resonance
  ( Hi Al, Set it as before. I will also use the capacitor as well. Richard)

•  video  - Series LCR Circuit, Resonance
  ( Hi Al, I will show resonance with the the series RLC circuit. Use L=4.25 mH and C=0.47 uF and the lightbulb so they can see the light get brighter. Thanks Richard )
