This was really helpful. I couldn't understand a thing when my professor taught me because he was explaining in a complex way and included too many unnecessary details but you explained it in the right way. Thank you for uploading this video.

How wie can calculate the Chang of length, for example if the resistance changs itself

I am looking for a video on:
R=KL/CMA

i have a test question with that formula and they ask what is K.

Thank you

Hi, thanks a lot for this video. Just a confirmation from you.
From the first example, assuming Vs = 5V, R0 = 120 Ohm and Delta R =4 Ohm we should get i_0 = 41.67 mA and i = 40.32 mA. Correct?

Please answer this question:
A strip of high-strength steel has a length of 30 cm and cross section of 1mm by 20mm. The modulus of elasticity is 200GPa. Determine the change in resistance when 1000 micro-strain experience by the steel. Gauge factor of 2.10.

Hi! Thanks for the video! Am i correct in saying that applying a strain increases L & rho and decreases A which all have a combined approximately linear effect in increasing resistance. It's this resistance change which is measured and analyzed to find out what the strain was. ? Thanks again :)
