# Discuss how you can identify which resistances are in series and which ones are in parallel in a series-parallel circuit.

Series – Parallel Resistive Circuits

Discuss how you can identify which resistances are in series and which ones are in parallel in a series-parallel circuit.

How might this affect how you measure current and voltages in the circuit with a digital multimeter?

Discuss the difference between voltage division and current division and how each can be used to analyze a series-parallel circuit.

Analysis:

For Laboratory Application Assignment on pg. 204 – 205 examine Fig. 6-50.

Perform calculations for:

Rt (total equivalent resistance)

It (total current supplied by voltage source)

V1 (voltage across R1)

V2 (voltage across R2)

V3 (voltage across R3)

V4 (voltage across V4)

VAB (voltage between points A and B)

I2 (current in R2 branch)

I3 (current in R3 branch)

P1 (power dissipated in R1)

P2 (power dissipated in R2)

P3 (power dissipated in R3)

P4 (power dissipated in R4)

Pt (total power dissipated by the series-parallel circuit)

Scan all calculations showing all work in a file called “Lab6_Analysis_StudentID”.

Simulation:

Construct the series circuit in Fig. 6-50 with MultiSIM.

Measure the values:
