In the circuit shown below,
(a) Find Ra = R5 || R6 and Rb = R3 || R4.
(b) Redraw the circuit consisting of Vs, R1, Rb, R4, and Ra. Find the equivalent resistance Req
seen from the voltage source.
(c) Find the current I1 through R1, Rb, R4, and Ra.
(d) Find the voltage across R1, voltage across Rb, voltage across R4, and voltage across Ra.
(e) Find the voltage V1, voltage V2, and voltage V3.
(f) Find the currents I2, I3, I5 and I6.
Vs=16;
R1=2000;R2=4000;R3=12000;R4=600;R5=4000;R6=6000;
Ra=P([R5,R6])
Rb=P([R2,R3])
Req=R1+Rb+R4+Ra
I1=Vs/Req
VR1=R1*I1
VRb=Rb*I1
VR4=R4*I1
VRa=Ra*I1
V1=Vs-VR1
V2=V1-VRb
V3=V2-VR4
I2=VRb/R2
I3=VRb/R3
I5=V3/R5
I6=V3/R6
