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. Made with code · Remix it to build your own circuit!

점이 옮겨 가요

✖️ 2.4 × 3 은 왜 7.2 일까요? 점을 빼고 24 × 3 = 72 를 구한 다음, 소수점 아래 자릿수만큼 다시 점을 찍으면 돼요. 두 수가 모두 소수면 자릿수를 «더해서» 찍습니다 — 0.6 × 0.7 이 0.42 인 까닭이 여기 있어요. 1보다 작은 수를 곱하면 오히려 작아지는 것도 직접 만들어 볼 수 있어요. ➗ 나누기 탭에서는 반대예요. 자연수로 나누면 소수점이 있던 자리 그대로 내려오고, 10으로 나누면 점이 왼쪽으로 한 칸 옮겨 갑니다. 🎯 마지막은 점을 뺀 숫자만 채우면 점은 앱이 찍어 줘요. 이 앱도 코드로 만들었어요 · 리믹스해서 100으로 나누기를 넣어 볼까요?

나누고 내려 쓰기

🪜 138 ÷ 6 을 세로로 풀 때, 왜 몫의 2가 1이 아니라 3 위에 설까요? 1은 6으로 못 나누니까 두 자리를 함께 봐서 그래요. 왼쪽부터 한 자리씩 나누고·곱하고·빼고·내리는 네 걸음을, 두 수를 바꿔 가며 눈으로 따라가 보세요. 418 ÷ 4 처럼 몫 가운데에 0이 서는 경우도 만들어 볼 수 있어요 — 못 나누는 자리에 0을 안 쓰면 그 뒤가 통째로 밀린다는 걸 그때 알게 됩니다. 📦 나머지 탭에서는 나머지를 가장 크게 만들어 보세요. 나누는 수보다 딱 1 작은 데서 멈춰요. 왜 그보다 클 수 없는지 그 자리에서 보입니다. 🎯 마지막은 몫을 자리마다 직접 채워 풀어요. 이 앱도 코드로 만들었어요 · 리믹스해서 두 자리로 나눠 볼까요?
