Title: Series Parallel Circuits contd.

1
Series - Parallel Circuits (contd.)
• ENTC 210 Circuit Analysis I
• Rohit Singhal
• Lecturer
• Texas AM University

2
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
• The less the load, the closer they are to 9V.

4
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.
