this is the circuit symbol of a cell. A single unit that generates electrical energy through chemical reactions. It has two terminals: positive and negative.
Once the chemical reactions that generate electricity inside the cell are depleted, it can no longer provide power
a single cell typically has a shorter lifespan or capacity compared to a battery, which is a collection of cells.
the longer line is typically the positive terminal, while the shorter one is the negative terminal
these are the circuit symbol for a battery
-------------
A collection of more than 1 cell connected together. It provides higher voltage or capacity compared to a single cell.
