A substance that produces an electrically conducting solution when dissolved in water. It's like the road on which our toy car (the galvanic cell) runs.
This is a laboratory device used to connect the oxidation and reduction half-cells of a galvanic cell. It's like the bridge that connects two parts of a city, allowing traffic (or ions) to flow between them.
The force that pushes electrical energy through a circuit, much like how gas propels your real car forward. In our analogy, it's what makes our toy car move!
