Positive Terminal of an Electric Cell
The positive terminal of an electric cell is the part of the cell from where the current flows out. It is connected to the positive terminal of an external circuit, such as a light bulb or a motor. The positive terminal is usually marked with a plus sign (+) on the cell.
Options:
a) Metal disc
b) Metal case
c) Metal cap
d) Metal base
Explanation:
The correct answer is option 'C' - Metal cap.
1. Metal disc:
A metal disc is usually found at the bottom of the cell. It acts as the negative terminal and is connected to the negative terminal of an external circuit. The current flows from the positive terminal to the negative terminal.
2. Metal case:
The metal case of an electric cell is usually made of zinc and serves as the negative terminal. It provides the structural support and protection for the internal components of the cell. The positive terminal is not associated with the metal case.
3. Metal cap:
The metal cap is located at the top of the cell and is typically made of a conductive material such as brass or copper. It is connected to the positive terminal of the cell and serves as the point from where the current flows out. The metal cap is usually marked with a plus sign to indicate the positive terminal.
4. Metal base:
The metal base of an electric cell is the bottom part of the cell that is in contact with the metal disc. It provides stability and support for the cell. However, it is not directly associated with the positive terminal.
Conclusion:
In summary, the positive terminal of an electric cell is the metal cap. It is connected to the positive terminal of an external circuit and is responsible for allowing the current to flow out of the cell.
