1. Series - Parallel Circuits (contd.) ENTC 210: Circuit Analysis I Rohit Singhal Lecturer Texas A&M University

2. Voltage Divider Supply What’s the value of V1, V2 and V3? 9V = V 1 > V 2 > V 3 R1R1 R2R2 R3R3 V3V3 V2V2 V1V1

3. Voltage Divider Supply We cannot calculate V 2 and V 3 unless we know what load is connected to them The less the load, the closer they are to 9V. R1R1 R2R2 R3R3 V3V3 V2V2 V1V1

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.
