Intro - what's up with cells & batteries? 🔋
- Electric currents? They’re more than just the stuff that powers your phone; they can create a chemical reaction!
- Real-World Example: Think of a superhero like Thor. Just like he uses his thunderbolt for various purposes, electric currents can produce a chemical effect that's used in extracting precious metals from ores!
Chemical industries 🧪
- Electric currents can be used for some cool chemistry stuff, like
- Extracting ores (getting metals from rocks)
- Purifying materials (making them pure & shiny)
- But, hold your horses! 🐎 We aren't diving deep into this chemical saga today.
Our focus - cells as energy storage devices 🔍
- Electric cells: Think of them as mini energy storages.
- What they do: Store energy in a chemical form & release it as electric energy when needed.
- Real-World Example: Imagine your body as a battery. You eat food (store chemical energy) and then use it for running around (using the energy)!
DC (direct-current) alert! 🔌
- Cells are like your no-nonsense friends; they're direct. They operate as DC devices.
- What's DC? It means the energy flow (charge) is straight-up, in ONE direction. No zigzagging around.
- Journey of an electron (little buddies carrying charge)
- Says goodbye at the negative terminal of the cell.
- Travels around the circuit (like a world tour 🌍).
- Comes back home to the positive terminal of the cell.
