Homework Statement A car passes you on the highway and you notice the taillights of the car are 1.22 m apart. Assume that the pupils of your eyes have a diameter of 7.1 mm and index of refraction of 1.36. Given that the car is 14.1 km away when the taillights appear to merge into a single...

Thanks for all the help guys, I figured out the answers for I1 and I3.

Thanks for all the help so far, but I still can't get the answer. I decided to make three loops Left loop was ε1-R1I1+R2I2-ε2-R4I1=0 Right loop was ε2-R2I2-R3I3=0 And the whole loop was ε1-R1I1-R3I3-R4I1=0 Junction was I1=I2+I3 Solving through and using elimination I got up to...

For the junction equation is I1= I2+I3 ?

Homework Statement The circuit in the figure is composed of two batteries (ε1 = 9.0 V and ε2 = 5.0 V) and four resistors (R1 = 110.0 Ω, R2 = 40.0 Ω, R3 = 30.0 Ω, and R4 = 50.0 Ω) as shown. 1). What is the current I1 which flows through R1? 2). What is the current I3 which flows through R3...
