It is possible if e.g. it's a 2 V battery with a 4 Ω resistor in series (which could be the internal resistance of the battery). | |
| Mar 21, 2022 at 10:02 | comment | added | ringo | I will correct it. If the gray part is a battery connected with the + pole facing down, is this possible or not? | |
| Mar 21, 2022 at 9:46 | comment | added | Puk | This case is certainly possible. For example, this will happen if the gray part is a 1 Ω resistor. I'm not sure what you mean by "no grayed out parts". If you mean there is nothing connected to your device (i.e. the device is open-circuited), then this couldn't happen because there would be no current flow. | |
| Mar 21, 2022 at 9:38 | comment | added | ringo | Thank you for answer. Then, since this case is a part of the whole circuit (due to the grayed out part in the figure), is my question a possible case? Conversely, if there are no grayed out parts, is this something that can never happen? Thank you. | |
