WebSep 4, 2024 · If you connect a 75 Ω load to the generator, the internal voltage source now sees the internal resistance and your load in series as its load. That means the load on the internal voltage source is 77 Ω. The current is (50 V)/ (77 Ω) = 649 mA. The drop across the unavoidable internal resistance is (649 mA) (2 Ω) = 1.3 V. Jun 1, 2024 ·
