The potential of positive terminal of electric cell is low.Is it true or false?
Answers
Answer:
the answer is False
Explanation:
The positive terminal of an electric cell is at higher potential with respect to its negative terminal.
Answer:
False, reason is stated below.
Explanation:
A DC or AC power supply has two or more terminals (such as points) if it is grounded.
For simplicity, assume that the cell or battery has two terminals. One of them is (+) and the other is (-). In the case of ordinary current (not real current), current always flows from high potential to low potential.
These potentials can be different when measured from a third reference point. Therefore, the terminal with low potential is defined as 0V and the others as positive terminals. Therefore, the difference between high and low potential is always positive. For 12V battery
1) Since the positive terminal is 12V and the negative terminal is 0V, the potential difference is 12V for 0-12.
or 2) since the positive terminal is 24V and the negative terminal is 12V, the potential difference is 12V from 24 to 12.
Therefore, the potential at the positive terminal is higher.
