Understand the anatomy of an electric cell and how cells combine to form a battery.
Clarification on common terminology.
Explanation of positive and negative terminals.
An electric cell is a compact, portable source of electrical energy. It powers small devices like your torch, wall clock, or TV remote.
Look closely at a standard cell. You'll notice a small protruding metal cap on one end. This is the positive terminal of the cell.

Fill in the blank exercise on cell terminals.
An electric cell is a portable source of electrical . All electric cells have two . The metal cap of an electric cell is the terminal. In contrast, the flat metal disc serves as the terminal. For many devices, we often need to connect multiple cells to form a . In this arrangement, the positive terminal of one cell must be connected to the negative terminal of the cell.
How to connect cells to form a battery.
For many devices, a single cell doesn't provide enough energy. When we connect two or more cells together, we create a battery. Connecting multiple cells provides energy for a longer time or gives more power to the device.
