When Electricity Flows

🔌 How is electric current decided? Just divide voltage by resistance! 6V divided by 2Ω gives 3A. Raising voltage increases current, while raising resistance decreases it. Watch lightbulbs brighten or dim and see how simple division reveals the current! 💡 Next, see how lightbulbs connect. A single line is series, while branching paths make parallel. In series, removing one light turns both off, but in parallel, the other stays on! That's why one light going out at home doesn't turn off every room. 🧲 Finally, explore electromagnets! Wrap wire and run current through it to stick paperclips. More current or coils mean more paperclips! But switch it off? They all drop—electromagnets are only magnetic when electricity flows.
