Millikan's Apparatus allows for the atomization of a latex solution into tiny spheres, while the rubber hose charges them with static electricity. The spheres are then inserted in a cell formed by two charged plates. When the voltage between the plates is reversed, the particles are drawn to one plate or the other.

A. Without Power Supply

The rubber hose charges the particles and they are then placed between two charged plates in a cell. By reversing the voltage between the plates, the particles are drawn to one side or the other. A small telescope with a graticule is used to observe their motion. The calculation of the charge on a single electron can be determined by measuring the potential of the cell plates and plotting the velocities of the spheres. External power sources need to be connected.

Includes: 

  • Sockets for connecting to 12V.AC / DC at 3A for illuminator
  • Sockets for connecting a high voltage DC power supply
  • Knob to adjust cell voltage from 0-300V.DC
  • Switch to reverse voltage polarity
  • Sockets for a student bench meter or multimeter

B. With Power Supply

Using a rubber hose, a static charge is induced upon the spheres before they are introduced into a charged plate cell. By reversing the voltage between the plates, the particles are attracted to one or the other. The movement of the spheres can be observed through a small telescope with a graticule, and the built-in power sources allow for easy measurement of the charge on a single electron by plotting their velocities. 

Includes:

  • Switch to reverse the polarity on the cell
  • Knob to adjust the cell voltage from 0-300V.DC 
  • Sockets for a student bench meter or multimeter
Dimensions:  300m (L) x 165mm (W) x 165mm (H) 
Power: 1.6kg

An Elegant and Secure Solution for Remote Control Storage
Color: Red
One of the first aspects I noticed was the impeccable fit of the case. It cradles the remote with precision, ensuring a snug and secure hold. This tight fit protects the remote from accidental drops and minimizes the risk of misplacement—a common concern in busy households or shared spaces. The peace of mind this provides is genuinely appreciable. The case's construction is made of lightweight and durable material. Despite its slim profile, it offers reliable protection against daily wear and tear, keeping the remote pristine. This balance between portability and sturdiness is a testament to the quality of its design. Another thoughtful feature is the minimalist aesthetics. The case seamlessly complements the Apple TV remote’s sleek design, blending harmoniously with modern decor. It’s a small yet impactful detail that enhances the overall visual appeal of my entertainment area. Moreover, the case is straightforward to install and remove. This user-friendly approach ensures I can switch between setups or clean the remote with minimal hassle—a convenience that should not be overlooked.

Perfect remote case!
Color: Red
100% worth every penny for this! Apple seemingly makes their remotes from sheets of aluminum foil, if you fart to close to one, the wind will dent them. That being said- This case solves that. The fit and finish is apple quality (the quality of their other products, not the remote made of play doh), it doesn’t add much bulk, easy to use and snaps right in place, and has an almost soft feel with some grip so it won’t slide off the arm of a couch or recliner. The red band of color is great for making it stick out and easier to find as well. 10/10 would recommend!

Exceeded expectations.
Color: Blue
This simple yet effective case covers the back with a clear plastic window and fully encases the remote's edges. My kids dropped the old remote far too many times, and being made of aluminum, it dented and the IR piece in the front broke. I even bought a new remote, BUT, once I put this case on the old one (gluing the IR window back on), I discovered I no longer need the new remote, as this will last a long long time. I wish I had bought this from the start. Why didn't I? because I thought it would make it bulkier. Sure it's a little wider, but feels pretty good in the hand, and the weight difference is negligible.
