ECT 122 Week 5 iLab #3
1. Determine the load voltage by deriving an equivalent circuit for the circuit below.
Reduce the R1, R2, and R3 combination to a single equivalent resistance. Also,
reduce R4 and RL1 to a single resistance.
R1-2 = R1+R2 = 470 + 220

3. Calculate the component voltages and branch currents for the circuit shown in Figure 6.40, along
with the values of IT and RT.
Net resistance of first branch = R1+R2 = 10k+3k = 13k I
