Is it incorrect to say "when the voltage arrives to point X" To my understanding, voltage is potential difference. It can't be defined as "arriving" to some place in the circuit. Current can arrive. Voltage is "just is". It's there. It doesn't move. It creates the borders for where the currents flow. The reason I'm asking is because I saw a classmate writing that, and it's supposed to be a legit solution supposedly. What do you think? Am I right, or what?
