Electric Circuits: Understanding Series Circuit with Three Resistors - HELP!

AI Thread Summary
To solve the problem of three resistors in series, the equivalent resistance is calculated by simply adding the resistance values together. In this case, with three resistors each at 9 K ohms, the total resistance would be 27 K ohms. The potential difference from the battery is 1625 mV, which can be converted to volts for calculations. Understanding the basic principles of series circuits, including how to handle resistance, is crucial for solving related quiz problems. Mastering these concepts will help clarify any confusion regarding electric circuits.

electric circuits-- HELP!

Ok, so I have a quiz on this material tomorrow and I am thoroughly confused. My teacher gave us review problems and I keep getting them wrong. One of them was:
Answer the below questions for a case in which three resitors are positioned in a series with a battery and each of the three resistors is 9 K ohms. The battery potential difference is 1625 mV.
(a) What is the equivalent resistance of the circuit?

Please help me figure out where to start... I am so confused.

First you should review what to do with resisters in a series or parallel. If in a series do you add them or do you add the inverse? There should be something in your book that mentions what to do.
 

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...
