... What would happen if a third bulb was put in parallel with the other two? Pat, Leslie, and Robin disagree. Pat says that the first two bulbs would get dimmer, because the current through them would decrease in order to satisfy Kirchhoff’s node law. Leslie says that one-third of the current would go ...
