AI Thread Summary
To convert a meter with a 5k Ohm internal resistance and a full scale of 50 microA into a 1000 range voltmeter, a resistance of 19.95 mega Ohm must be added in series. For the electrical supply line loading question, when the voltage is reduced from 480V to 240V while maintaining a peak power output of 2000 kW, the supply line losses will increase by a factor of four. The discussion also touches on the importance of proper forum etiquette, questioning the placement of the topic in the correct section. Overall, the thread emphasizes the calculations needed for electrical measurements and the implications of voltage changes on power loss.

1. An electrical meter has an internal resistance of 5k Oh, and registers full scale of 50 microA. How many mega Ohm to insert in series to turn meter into a 1000 range voltmeter?

2. An electrical supply line loading question. Some large piece of electrical equipment ahs a peak power output of 2000 kW. If this is maintained, but voltage changed from 480V to 240V, by what ratio will supply line losses change


Thank you.

Why isn't this posted in the Homework section? Does anybody ever read the rules?
 

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...
