    Parallel Series
AI Thread Summary
In series circuits, the current remains constant through all components, while the voltage varies across each resistor, leading to different potential differences. In parallel circuits, the voltage across each resistor is the same, but the current can differ based on the resistance values. The confusion often arises from the relationship between current, voltage, and resistance as described by Ohm's Law. Understanding these principles allows for accurate calculations of voltage and current in both configurations. Mastery of these concepts is essential for grasping the behavior of electrical circuits.

Homework Statement


I'm a little confused, in a series and parallel circuit, does it make sense if i say that the current through 2 separate resistors is the same but the potential difference is different and also is the amount of potential energy lost?? It's this that's getting me confused with the concept..

The current through two series components is the same. The voltage across two parallel components is the same.

But for the series, does that mean that the voltage is the same for both resistances?
And for the parallel one, if the voltage is the same, does that make the current equal as well?

No and no. If you combine the two rules mentioned by Berkeman with ohms law you can work out what the voltages are for series resistances with a known total voltage across them, or you can work out the currents for parallel resistances with a known total current going through them.
 
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 .
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...
