Voltage Divider Supply

• Whats the value of V1, V2 and V3?
• 9V V1 gt V2 gt V3

3
Voltage Divider Supply

• We cannot calculate V2 and V3 unless we know what
  load is connected to them
• The less the load, the closer they are to 9V.

Potentiometer
5
Voltage Sources

• Two voltage sources of different ratings may not
  be connected in parallel.
• Why?
• Series operation, however, is permitted.

6
Current Sources

• Two current sources of different rating may not
  be connected in series.
• Parallel operation, however, is permitted.
