    Circuit Equivalent
AI Thread Summary
The discussion focuses on using Thevenin's theorem to find the current in a 3-ohm resistor within a parallel branch of a circuit. The original poster expresses doubt about the applicability of Thevenin's theorem, suggesting that it only works for series components and that a cut cannot be made across terminals A and B. They propose that Norton's equivalent circuit might be necessary to solve the problem instead. Other participants offer encouragement and suggest reviewing similar circuits for guidance. The conversation highlights the challenges of applying Thevenin's theorem in this specific scenario.

Homework Statement


use thevenin's theorem to find the current in the 3 ohm, parallel branch, resistor

Homework Equations


Thevenin equivalent circuit, voltage divider rule

The Attempt at a Solution



I don't think its possible, since thevenin's theorem ends up with a voltage source and a resistor in series, you can only find currents and voltages in components that are in series. In this circuit there is nowhere to make the cut and split the circuit across terminals A and B. Normally you'd need Norton's equivalent circuit to find the current in the 3ohm resistor. Am I right, or is there actually a solution using thevenin's?

Could anyone solve this problem?

try and study it from the url. The circuit is quite the same as yours.
 
thanks for that, useful!
 
ur most welcome! :D
 

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}...
