22)What is the total charge of 75kg of electrons. 25) You are given a number of 10Omega resistors, each capable of dissipating only 1W without being destroyed. What is the minimum number of such resistors that you need to combine in series or parallel to make a 10omega resistance that is capable of dissipating at least 5.0 W? For 22 do I just divide 75 by the still mass then multiply by the electon's charge? And for 25 I am completely stumped. A lot of detailed help before tomorrow would be swell.
