Question

У зажимов аккумулятора не оказалось пометок о том что, какой из них "плюсовой" и какой "минусовой". Можно ли узнать это, имея компас?

Answer 1

Можно, нужно просто поднести к зажимам. И тогда по системе то что плюс не взаим с плюсом и минус не взаим с минусом, а минус взаим с плюсом. Посто у компаса есть полюса южный и северный

Answer 2

Identifying Battery Polarity with a Compass

If there are no markings on the battery terminals indicating which is positive and which is negative, you can use a compass to determine the polarity.

Using a Compass to Identify Battery Polarity:

You can use a compass to identify the polarity of the battery. Here's how you can do it:

1. Place the Compass Near the Battery: - Hold the compass near the battery without touching the terminals.

2. Observe the Compass Needle: - The compass needle will point towards the north, which is the Earth's magnetic north.

3. Identify the Polarity: - The end of the compass needle that points towards the battery terminal is the negative (-) terminal, and the opposite end is the positive (+) terminal.

This method allows you to determine the polarity of the battery using the Earth's magnetic field.
