287. Problem 22.33P (HRW) A 100 W lamp operated on a 120 V circuit has a current (assumed steady) of 0.83 A in its filament. We have to find the time in which 1 mol of electrons will pass through the lamp. |
Solution: Click For PDF Version The current flowing through the filament of the lamp is 0.83 A. Therefore,
0.83 C pf charge carried by electrons passes through the filament per second. As
the charge of an electron is
The time required for one mol of electrons, that is
As we have |
