How will you identify the positive terminal of a battery if it is hidden in a box and you can only see two of its leads.

Expert Answer:

Both the leads of the battery can be dipped into a single piece of potato for long time. After that, it can be observed that there is green coloration near one of the terminals. This is the positive terminal and the other one is the negative terminal.
