High Voltage Technique The puncture strength of the insulator in a coaxial cylindrical electrode system with outer cylinder radius r2=10 cm varies from inner cylinder radius r1 [cm] to Ed=30+10/r1 [kV/cm]. a) Determine the limits of the values ​​that r1 can take in order to apply 80 kV to the system. b) Calculate the maximum field strength of the most suitable system for U=80 kV. c) For r1'=0.5 cm, r1"=3.5 cm and r1"'=8.5 cm, evaluate the system in terms of discharge events at U=80 kV. ANSWERS: a) 0.63 cm<r1<6.93 cm b) Emax=21.75 kV/cm

Before starting the experiment on Coulomb's law experiment you had a lesson on electrostatic phenomena. You learned that in a static situation, if there is excess charge on a conductor, 1. it keeps leaking from the surface to surrounding atmosphere until the whole amount of excess charge is gone 2. it remains concentrated at the center part 3. it spreads over the surface of the conductor 4. it's under a constant motion throughout the conductor surface

Task #1: According to Coulomb's Law F either charge increases(multiply) or decreases (divide), the force increases by the same factor that the charge increases or decreases. is directly proportional to the product of the charges. As elect F = k• d2 elect Complete the following statements using the statement above: 1. If Q, is doubled, then Flect is 2. If Q, is tripled, then Falact is 3. If Q, is halved, then Fect is is 4. If both Q, and Q, is doubled, then Falect! is elect 5. If Q, is doubled and Q, is tripled, then F elect 6. If Q, is tripled and Q, is halved, then F is
