That's what voltage is.Hm, true, voltage is impossible without current flowing because of how voltage is defined. No current <--> no voltage, and voltage is something that doesn't exist. I never thought of it like that before.
Incorrect. Voltage is strictly an excess or shortage of electrons. Current flow is not necessary for voltage to exist.
You really do need to take some electric theory courses.
