Please don't post unrelated questions to this group. It would be better for you to post this in a more appropriate group (like Physics) and then post a link to it in any of the chat windows if you find no one available to help out in that group.
This helps keep the groups on topic.

since the current remains same, the total voltage is
IR = 20x110E-3 = 4.4 V
