in this problem, we are asked to kill Claire. The potential difference between point and B, that is Well, maybe a sense of the circuit is open their point and be so there will be no current through the Apache or potential difference 4.0 world and the resistor off resistance 10.0. So the current in the closed loop will be I opposed to 12 points to a world divided by Ari, where the saris 2.0 plus 4.0 So the squaring can beat Inez I close to 12 points. It'll hold divided by 6.0 omega. This with us I equals to 2.0 aren't bad? No. For open loop, we can, right. We have vehicles to 4.0 world minus tryinto 4.0 omega Setting the well you're fired from this equation. Weaken white. We have b equals 24.0 world minus 2.0 impair into 4.0 omega. So this with us, we have vehicles, too. Minus 4.0 Worked our since the surgeon potential is taken from Toby on this potential changes here in that Get you s so we can conclude that point a his head. High potential. So thank you.
