(b) At what temperature will atoms of a gas have an average kinetic energy equal to this needed electrical potential energy?
- The first Leyden jar was probably discovered by a German clerk named E. Georg von Kleist. Because von Kleist was not a scientist and did not keep good records, the credit for the discovery of the Leyden jar usually goes to physicist Pieter Musschenbroek from Leyden, Holland. Musschenbroek accidentally discovered the Leyden jar when he tried to charge a jar of water and shocked himself by touching the wire on the inside of the jar while holding the jar on the outside. He said that the shock was no ordinary shock and his body shook violently as though he had been hit by lightning. The energy from the jar that passed through his body was probably around 1 J, and his jar probably had a capacitance of about 1 nF. a. Estimate the charge that passed through Musschenbroeks body. b. What was the potential difference between the inside and outside of the Leyden jar before Musschenbroek discharged it?A 2L long wire of cross section A is attached with wire of length L with cross 2 Volt 10 Volt AZ 2A section area of 2A made of same material. 2L The potential at one end of the system is 10 Volts and the potential at the other is 2 Volts.
