Report: Electric Field Mapping Andie Zoeller 09/09/2014 Essence: The objective of this lab was to map out certain points of voltage that were determined by the equipotential surfaces. By doing this, with the probe on a multi-meter, we were able to see where the equipotential lines were at in accordance to the objects (metal cylindrical conductor, metal rectangular conductor, etc.) With this gathered information we were able to point out where the lines of the electric field were. We

David Zendejas Period 2 April 11, 2015 Honors Physics Static Web quest Electric Field Hockey The whole point of the game is to make the puck go into the net, but the only thing to get the puck moving is by adding protons and electrons to the ice. The game makes it so that you can change the charge on the puck’s charge to either positive or negative. If the puck is positive you can add protons near the puck so the puck and proton would repel

E1 - Electrostatics (Potential & Field) Date: 26th of August 2014 Partners: Luke Silveira and Tivanka Anandappa Introduction: This practical involved investigating the behaviour of equipotential and electric field lines between two electrodes (which represented the a parallel plate capacitor). Furthermore the effect of adding a conductor and an insulator between the two electrodes was explored to determine the electric potential produced from these configurations. The setup involved three

Abstract- A home-made dc sputtering is characterized by cathode potential of 250-2000 V and sputtering gas pressures of (3.5×10-2 – 1.5) mbar. This paper studies in experiment the breakdown of argon, a uniform dc electric field at different discharge gaps and cathode potentials. Paschen curves for Argon are obtained by measuring the breakdown voltage of gas within at different target cu,Au,Ag, vacuum chamber . The Paschen curves in Ar gases show that the breakdown voltage between two electrodes

edu Abstract—Accurate and high throughput cell sorting enabling technology in molecular and cellular biology, biotechnology and medicine. We classify these technologies as either active or passive. Active systems generally use external fields (e.g., acoustic, electric, magnetic, and optical) to impose forces to displace cells for sorting, whereas passive systems use inertial forces, filters, and adhesion mechanisms to purify cell populations. Cell sorting on microchips provides numerous advantages

Applications in medicine Moreover, toxins pile up in the body, especially outside of the cells due to poor bio-electric membrane voltage, which makes it possible for the toxins to stick to the membrane. This activity inhibits the natural flow of water into the cells as well as exit of nucleic waste out of the cells. As a result, the functioning of the cells is compromised until the level whereby toxins penetrate the cell membranes and thus reaching a level whereby the process is irreversible. Moreover
