Electrical current and Resistance and Energy

AI Thread Summary
The discussion focuses on calculating resistance and energy loss in an electrical circuit. Using the formula R = V/I, a resistance of 20 ohms is determined from a 12V battery and a current of 0.60A. For energy loss, the participant initially struggles but realizes that multiplying current by voltage and time gives the correct energy calculation. The energy lost by the battery in one minute is derived from the power formula, leading to a clearer understanding of energy transfer in the circuit. The conversation highlights the importance of correctly applying formulas in electrical calculations.

Homework Statement


A 12v battery causes a current of .60A through a resistor. a) what is the resistance? and b) how many joules of energy does the battery lose in 1 minute?


Homework Equations


R= V/I; I= Q/T


The Attempt at a Solution


I understand part A that is just algebra and I got 20 ohms,
but I don't know how to translate this into energy lost. Can I use that second equation somehow with 60 seconds?

never mind i figured it out i was dividing instead of multiplying!
 

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 '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 .
