So we are given point A and B on every 0.150 minutes, which is equal to 30 seconds. So every 30 seconds we have 5.11 time. Stand by eight, then about 18 chlorine minus ions going on from B to A. There are 3.24 I'M stand by 18. See a topless ion scoring. Now we want to find out the amount of current in this case. No, let's consider this case now because chlorine minus is a negative ion. We can instruct thing off this Flav charge as going from B to A at the rate of 500 and you know 5.11 times two is 18 ions, but it's less each charge instead ofthe minus the charge which chlorine minus carries so we can insert. Think off this says 5111 time Stand by waiting ions off. Bless E charge. Morning In moving from B to a Now we can see that if you think of it like that from B to A, we have 5.11 time stamp are 18 plus eat ion scoring. I'm for calcium. Each one has a charge off to eat. Where is the electron charge? Hence the amount of charge carried from B to a due to the calcium ions will be two times 3.24 times turned 18 time's charge off each electron. Hence the total charge carried will be by the chlorine ions. That would be 5.11 time stamp are 18 times the charge of LeBron e going from B to a mind you on because of the Florey Because of the calcium ions, that would be 3.24 time stamp are 18 times two because each ion carries two. Thank you. Try still attract charge on notice that I have put a plus sign here because both of them are going from b teau eh? And the current is simply tell Doc your little daddy, Which is it in this case, 4.11 times one by 18 place two times 3.24 times temp are 18 times the electronic charge, which we know is 1.6 times standby minus 19 Coolum divided by 30 seconds. We know that cooling by second is Tampere. So we got our units right. And if you play this number into a calculator, you'll see that it is 62. It's actually 0.62 which turns out to be 62,000,000 amperes, of course. And this is the amount of current which flows from B tow A. Remember, the direction of the current is super important. You could also think off. This has minus 62,000,000 amperes going from A to B.
