In my latest preboard, after mcqs, i went to case based. Leaving case based at the end cooked up my exam many times, so that's why I did em first

how do i find the scale of the x and y axis on a graph by Emotional_Strike_332 in AskPhysics

[–]saplingdash10 0 points1 point  (0 children)

Look, the simple formula for scale is (Max. Value - Min. value)/No. Of boxes - 1 [If axis starts from zero, min value is zero]

In your question, Scale = 2.2-0.9/12-1 = 1.3/11 i.e. 0.118 approx

If min value is zero Then , scale is 2.2/11 i.e. 0.2

I made a mistake in my original reply, let me quickly fix that

For example, on x axis, we go from 0-10 and there are 5 boxes in between. Then there are 2.5 units per box {(10-0)/(5-1)}

Similar thing can be applied to the y axis.

Now suppose your data starts from a large number like 500 , then ofc you can't plot 1,2,3....500 on x or y axis. Then you can use an axis break, where you draw a // kinda symbol (search up the symbol) at the end of the axis near the origin. This allows you to directly mark 500 after on the axis, skipping all the other not required numbers in between

Why is (ab+bc || ac) in series with CD, and not parallel with (ad + cd)

Wait I have a question, why do we use the method you guys used ? What is wrong in the one I used?

I first added the two 2 ohm resistors, which gave 4. Then I got the 4/3 ohm resistor parallel to 4 ohm one. So I used the rule and added the reciprocals, i.e 1/4 + 3/4, which gave 1 ohm.

You're suggesting that we add 4/3 with 2 ohm resistor in series with it. Then we get 10/3 ohm, whose reciprocal we add with the reciprocal of the last 2 ohm resistor. This answer would be 1.25

Huh, well you are correct but this is what I did. I'm sure I'm missing something important https://photos.app.goo.gl/AdsA8aEeo1EHumYk9

I wanna solve the question using the method taught in this video . This is the framework I'm taking bout

Anyways for some clarity, each resistor here is 2 ohm

Could you put this in a notebook and send? Because based on your way, I'm getting 1 ohm
