Two equal disks of external radius R and internal radius R / 2 are loaded with positive and uniform charge distributions o. The discs lie in parallel planes separated by a distance R, but with their centers located on the same axis, as shown in figure 2. Take this axis as Z, and as the origin of coordinates or the midpoint between the rings. 1. Obtain the expression of the electrostatic potential created by these distributions in the points on the Z axis. Where is the potential maximum? 2. Obtain the electric field expression for the points on the Z axis. How does the electric field fo z >> R? 3. Determine the work that must be done to bring a point charge q from the infinity to point O. 4. A particle of mass m and charge q> 0 is thrown from infinity through the Z axis. Ďetermine the speed with which the particle must be thrown so that at point O stay at rest. R/2

c. The operation of lamp-ballast circuit
In this System your primary element is sending 1v - 5v to your controller and our controller is sending 4mA - 20mA to your final Element. 1) The Primary Element is sending 2.8v. Your controller is reading 2.8v. The Controller sends 5.2mA to the Final Element but nothing changes in your Process Variable. What is wrong? Controller Final Element Transmitter Wire 2) The Primary Element is sending 12v. Your controller is reading 12v. The Controller sends 0mA to the Final Element. What is wrong? Controller Final Element Transmitter Wire 3) the Primary Element is sending 3.4v. Your controller is reading 0v. The Control is not making changes when necessary, what is wrong? Controller Final Element Transmitter Wire
