I need to solve exercise 57. I need to determine the voltage between points
B in diagrams (a) and (b).
What I think so far:
- The voltage on 10 ohm resistor is = 0.1A * 10Ω = 1V
- The current on 20 ohm resistor will probably be 0.1A too (I think, I'm not sure). In this case its voltage is 2V (0.1A * 20Ω)
- UAB = Upower-Ur1-Ur2 = 4.5V-2V-1V = 1.5 V
Is it correct?
Thanks for your help.
