    Transformer Work
Click For Summary
Transformer taps are used to adjust voltage levels, but the discussion clarifies that the correct voltage is 13200 V, not 200/480 V as initially thought. The confusion arose from a lack of sleep, leading to arithmetic errors. Participants noted that distribution transformers are typically step-down transformers, which explains the absence of a 200/480 V transformer in practice. Personal experiences with transformers in different voltage contexts were shared, emphasizing the importance of accurate voltage identification. Overall, the conversation highlights the significance of understanding transformer ratings and their applications.

In the question below i know 200/480 V is rated voltage at primary and secondary side of a transformer, but '13' is what i do not know. Also how does the solution work out? i have tried every possible thing. Thanks(Sorry if i could not phrase my question in accordance to the pattern)

It is not 13, 200 but 13200 V

omg! what was i thinking. Lack of sleep yesterday night may be causing this weird behavior .

Possibly:wink:.
I often make ridiculous arithmatic mistakes when I am sleep-deprived.

In practice, distribution transformers are always step-down transformers, so you won't find any 200/480 transformer.
 
I had good use for a 110 -> 220V transformer while living in a developing country...
But I grant that the nameplate didn't say 'distribution transformer':smile:
 

Thread 'Coulomb's force vs the Lorentz force'

Beams of electrons and protons move parallel to each other in the same direction. They ______. a. attract each other. b. repel each other. c. neither attract nor repel. d. the force of attraction or repulsion depends upon the speed of the beams. This is a previous-year-question of CBSE Board 2023. The answer key marks (b) as the right option. I want to know why we are ignoring Coulomb's force?

Thread 'Struggling to make relation between elastic force and height'

Hello guys this is what I tried so far. I used the UTS to calculate the force it needs when the rope tears. My idea was to make a relationship/ function that would give me the force depending on height. Yeah i couldnt find a way to solve it. I also thought about how I could use hooks law (how it was given to me in my script) with the thought of instead of having two part of a rope id have one singular rope from the middle to the top where I could find the difference in height. But the...

Thread 'Speed of moth related to Doppler Effect'

I treat this question as two cases of Doppler effect. (1) When the sound wave travels from bat to moth Speed of sound = 222 x 1.5 = 333 m/s Frequency received by moth: $$f_1=\frac{333+v}{333}\times 222$$ (2) When the sound wave is reflected from moth back to bat Frequency received by bat (moth as source and bat as observer): $$f_2=\frac{333}{333-v}\times f_1$$ $$230.3=\frac{333}{333-v}\times \frac{333+v}{333}\times 222$$ Solving this equation, I get ##v=6.1## m/s but the answer key is...
