Im a 9th grade student and we have a homework for variations. I realized that this formula was a combined variation, so it peaked my interest cuz I'm also into physics, and even though I spent all night trying to figure out this whole ohms and resistance thing, It was worth it cuz I managed to present it in our homework and I learned something new and fun. Thanks for making this video!

[@stepbystepscience]

You are very welcome! Glad you had fun learning.

[@KortMateo]

how did you use the scientific calc? idk how

[@stepbystepscience]

That would be hard to explain here, best to ask someone to show you on your calculator.

Will combining high resistance wires together end and end, but they aren’t touching in the middle reduce the resistance

Thank you sir l have understand that. Resistance. Resistivity but. How. Is. It temperature dependence on a conductor

[@stepbystepscience]

As the temperature of a conductor increases the resistivity and the resistance also increase. The equation assume a constant temperature.

[@purplehazeto]

how do you re arrange to solve for L in original equation of R=pL/a?

L=RA/p

[@sathyamargam9545]

Thanks sir

[@stepbystepscience]

You bet!

[@Sparky-vj2dq]

Great clear video but you might like to consider a future version expanding on resistivity. In this one you did give it in the units ohm-metres (which itself might benefit from explanation) which is fine for most electrical and lab work but in the electronic industry, especially where they make actual resistors and also print them as part of ceramic hybrid microcircuits, new people are often bemused to find data sheets and pots of material giving the resistivity of the contents in "ohms per square". And of course, the first question is "ohms per square what?".
