RINTERNAL = | ℰ - VTERMINAL | = | 9 V - 8 V | = 0.2 Ω |
I | 5 A |
REXTERNAL = | 12 Ω × 4 Ω | = 3 Ω |
12 Ω + 4 Ω |
ℰ = I × (REXTERNAL + RINTERNAL) = 5A × 13Ω = 65V
REXTERNAL = | 6 Ω × 10 Ω | = 3.75 Ω |
6 Ω + 10 Ω |
VEXTERNAL = I × REXTERNAL = 1.5 A × 3.75 Ω = 5.625 V
VINTERNAL = ℰ - VEXTERNAL = 6 V - 5.625 V = 0.375 V
RINTERNAL = | VINTERNAL | = | 0.375 V | = 0.25 Ω |
I | 1.5 A |
VINTERNAL = ℰ - VEXTERNAL = 1.5 V - 1.45 V = 0.05 V
I = | VINTERNAL | = | 0.05 V | = 0.1 A |
RINTERNAL | 0.5 Ω |
RLOAD = | VEXTERNAL | = | 1.45 V | = 14.5 Ω |
I | 0.1 A |
I = | ℰ | = | 12 V | = 1.143 A |
RINTERNAL + REXTERNAL | 10.5 Ω |
VEXTERNAL = REXTERNAL × I = 10 Ω × 1.143 A = 11.43 V
