AI Thread Summary
The discussion focuses on calculating current in a complex circuit, specifically at a 1.1Ω resistor. The equivalent resistance (Req) is determined to be 5.775Ω, with a first branch resistance of 4.203Ω and an upper branch resistance of 6.65Ω. The total current flowing through the circuit is calculated to be 3.1166A. Additionally, there are inquiries about the current and voltage drop across a 3.2Ω resistor. The calculations and analysis aim to clarify the behavior of current in the circuit.

Homework Equations


V=IR




The Attempt at a Solution



So far I have found that the Req=5.775Ω
The First Branch which contains 1.1Ω, 4.5Ω, and 10Ω has a resistance of 4.203Ω
The upper Branch has resistance 6.65Ω
The total Current I=3.1166a

How much current flows through the 3.2 Ω resistor ?

What's the voltage drop across the 3.2 Ω resistor ?

Thread 'Rolling without slipping on a curved surface'

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .

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...
