6)When electrons flow through a thin filament, the experience friction or resistance. This resistance causes hinderance to the electrons and hence make it difficult for the electrons to pass thereby making them lose the energy. This energy is emitted in the form of heat or light or both depending upon the material of the filament.
Hence the friction in the filament causes the conversion of current into light and heat energy.

Suppose that in an electron gun, electrons are emitted from a hot filament at point f and are accelerated by an electric field to an opening at o, as shown. The charge on an electron is (-e) where e = 1.6 times 10^-19 C. (a) If the voltage (same as electric potential) at point f is - 280 Volts, what is the potential energy of an electron at f? (b) The electrons come off the filament with very low velocity,...

Lightning occurs when there is a flow of electric charge (principally electrons) between the ground and a thundercloud. The maximum rate of charge flow in a lightning bolt is about 20,000 C/s this lasts for 100 μs or less. 1.How much charge flows between the ground and the cloud in this time? (Q= ? C) 2.How many electrons flow during this time? (n_e = ? )
