In the circuit shown below, let






Is=0.002;Vs=6;

R1=1500;R2=2000;R3=6000,R4=2500;R5=3000;

syms V1 V2

[V1,V2]=solve(-Is+V1/R4+(V1-Vs)/R1+(V1-V2)/R2,...

(V2-V1)/R2+V2/R5+(V2-Vs)/R3,V1,V2);

V1=vpa(V1,7)

V2=vpa(V2,7)

I4=V1/R4

I2=(V1-V2)/R2

I1=(Vs-V1)/R1

I3=(Vs-V2)/R3

I5=V2/R5

IVs=I4+I5-Is

I1a=-I3+IVs

Answers:

V1 =

4.936709

V2 =

3.468354

A. This rating indicates the number of minutes a new fully charge battery at 80° F (26.6° C ) can sustain a load of 25 amperes before the battery voltage draw at 1.75 volts per cell or 10.5volts for a 12 volt battery. B. This rating indicates the number of minutes a new fully charge battery at 70° F (21.1° C ) can sustain a load of 25 amperes before the battery voltage draw at 2.0 volts per cell or 12.2 volts for a 12 volt battery. C. Indicates how long  a battery can provide enough power to keep the ignition, head and tail lights, windshield wipers, and heater operating if the battery is fully charged. D.
