Answer:
Step-by-step explanation:
Short answer yes.
Suppose
R1 = 20 ohms
R2 = 30 ohms
R3 = 50 ohms
They are all connected in series and hooked to a 100v DC source.
The voltage across the 20 30 and 50 volt resistors will all be different.
If you mean can the 100v source vary. The answer to that is also yes, but a good steady output is usually what the manufactures come up with.
