All right, so i didn't have the picture included on the question that you sent to us, but i'm going to try to set this up the best i can based on what the paragraph is saying.
00:16
So it looks like we've got some sort of power source, and it's hooked up to a switch that starts out open, and then we close it.
00:26
And we first take the voltage reading of the power source while the switch is open, and we get a value for that, and i called that b1.
00:41
And there was a resistance.
00:44
There's an internal resistance on the volt meter of 9, which i called r2.
00:51
There's also another resistor, which i called r1.
00:55
And when that's closed, you're going to get a whole different volt.
01:00
Voltage reading, which i called v2.
01:04
So when closed, we're getting a different current than when open, which makes sense...
