find the next judge flowing through the capacitor. All we have to know is how many home a charge. It's on one electron, so one Elektronik charge is equal to negative 1.6 times 10 power negative. 19. Cool. So net charge Q. Is equal to end times e and being number of electrons. Number of electrons is 1.8 times 10 power. 20 Ah, nde when he left on a judge is 1.6 times 10 power. Negative. 19. I forgot. Negative sign there. So let's do the multiplication of 1.8 and 1.6, which is two point 88 times 10 Power one, which is equal to 28. I'm sorry about that. 28. 1 to 8. Cool. Um, let's round it off to two significant digits. That is 29 Coolum
