AI Thread Summary
To solve for unknowns in a complex circuit equation involving resistors in parallel, it is crucial to understand that the voltage across each resistor is equal, meaning Vs = V1 = V2 = V3. The equations provided, including the equivalent resistance formula and Ohm's law, are essential for finding the unknown values. The discussion highlights the need for additional information to solve for variables like R2, R3, i1, i3, and total current. Participants express appreciation for simplified explanations compared to their professor's teaching. Overall, grasping the concept of voltage in parallel circuits is key to progressing in the problem-solving process.

Find all the unkown R,I's, V's


Homework Equations


Reg=(R1*R2*R3)/(R1+R2+R3)
it=i1+i2+i3
V=IR

The Attempt at a Solution



All unknowns:
R2,R3,i1,i3 it,Vs,V1,V2

It seems that I need one more bit of information to solve any variables
i1 goes across R1, i2 goes across R2, i3 across R3

Hint: Since the three resistors are in parallel, what's the voltage across each? (And the battery voltage, for that matter.)
 
Since they are parrallel the voltage across each is equal to each other? Vs=V1=V2=V3 is this right?!? Also why is that?
 
Ok thank you knowing this concept this should be an easy one...I have another simple question though.I will post the picture and work in a new thread that I will pm you, can you just come teach my class for me? Your anwsers are so much more simplier then the ones provided by my professor.
 

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
