Why does loading a circuit cause a voltage drop? : r/electrical
We can also figure out the voltage drop across the 20-ohm load as well, using the same process. V = 0.1 * 20 We get V = 2. So, 2 volts will be across the 20-ohm load. And if you take a look at the individual voltage drops, you''ll see they equal the voltage of the power supply. 3 = 3. That''s voltage drop simplified.
