6. V = I × R = 3 A × 4 Ω = 12 V
7. I = V / R = 230 V / 9.2 Ω = 25 A
8. R = V / I = 110 V / 10 A = 11 Ω
9. V = I × R = (50 × 10⁻³ A) × 120 Ω = 6 V
10. I = V / R = 120 V / 12 Ω = 10 A
11. a) R = V / I = 9.0 V / 25 A = 0.36 Ω
b) Sound energy and thermal energy (heat).
12. V = I × R = 1.5 A × (2.5 × 10³ Ω) = 3750 V
13. Total voltage = 4 × 1.5 V = 6 V; R = V / I = 6 V / (25 × 10⁻³ A) = 240 Ω

Parent Tip: Review the logic above to help your child master the concept of resistance calculations worksheet.
