Is voltage the same in parallel circuits with different resistance values?

AI Thread Summary
In parallel circuits, the voltage across each branch remains constant and equal, regardless of the resistance values of the resistors. This means that Vt = V1 = V2 = V3 holds true for all resistors in parallel, not just those with the same resistance. The confusion arises from the fact that while the voltage is the same, the current varies based on the resistance, as described by Ohm's law (V = IR). Therefore, using resistors with different values does not change the voltage across them, but it does affect the current flowing through each resistor. Understanding this distinction is crucial for analyzing parallel circuits effectively.

Homework Statement


I have to write about voltage within a parallel circuit and the formula for voltage in parallel is Vt=V1=V2=V3. But I was wondering if that's only the case if the resistors have the same resistance becasue I used resistors with different values

Homework Equations


V1=V2=V3

The Attempt at a Solution


The answer is yes the voltage across each branch is the same only when the resistors are the same value. Becasue when you use resistors with higher/lower resistance the current flow is different. (higher Ω Lower I) so using Ohm's law V=IR the voltage will be different if resistors with different values are used in parallel.

This is completely incorrect. See if you can figure out why

WOW!. My bad, I calculates something wrong. Vt=V1=V2=Vn...

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...
