In the following circuit potential at point

WebbThe answer is no. The vertical test whether the two resistors are in series or not, is remember that they need to have the same current flowing through them. That's the definition of series. So, I would imagine a small current flowing over here and see if that entire current flows here. If it does, they are in series. If not, they're not in series. Webb12 juni 2024 · The positive terminal of a battery is called the terminal of high potential because a unit charge at that point would have high electric potential energy.
