👀 Sample — Ohm's Law, Power & Energy
- V = I × R → I = V ÷ R, R = V ÷ I.
- P = V × I = I² × R = V² ÷ R.
- Worked example: 6 Ω load on 24 V → I = 24 ÷ 6 = 4 A.
🃏 Sample flashcards
- Ohm's Law? → V = I × R
- Binary 1010 in decimal? → 10
- How many distinct values can 8 bits represent? → 256
…plus 14 full topics and 100 cards in the complete pack.
