Output Voltage
8.00 V
Steps
1. Voltage Divider Formula: Vout = (R2 / (R1 + R2)) × Vin
2. Vout = (2000 / (1000 + 2000)) × 12
3. Vout = (2000 / 3000) × 12
4. Vout = 8.000 V
5. Total resistance: Rt = R1 + R2 = 1000 + 2000 = 3000 Ω
6. Current: I = Vin / Rt = 12 / 3000 = 0.004000 A
7. Power in R1: P1 = I² × R1 = 0.004000² × 1000 = 0.016 W
8. Power in R2: P2 = I² × R2 = 0.004000² × 2000 = 0.032 W
9. Total power: Pt = P1 + P2 = 0.016 + 0.032 = 0.048 W
10. Voltage ratio: Vout / Vin = 0.6667 (66.7%)
Formulas
Voltage Divider:
V_out = V_in × (R₂ / (R₁ + R₂))
Current Divider:
I₁ = I_in × (R₂ / (R₁ + R₂))
I₂ = I_in × (R₁ / (R₁ + R₂))
