Wheatstone Bridge Problem

Показать описание

Physics Ninja shows you how to solve for an unknown resistance using a Wheatstone Bridge. We first use Kirchhoff's rules to get an expression for an unknown resistance and then look an at example problem

Example 1- 750 ohms
Example 2- 55.5 ohms
Thanku so much for that explanation

just going to be more truthful right now. You are the only person who has been able to explain this to me😭😭😭😭😭😭, thank you so much sir. God Bless You. Please don't stop bringing out videos like these. Thank you so much sir.

Thanks so much! My university professor did not explain this well at all, but with this video I now completely understand it.

TheVirtualLab

Simple and concise explanation. Thanks.

tyronekim

thank youu so much I finally see why those potential differences are equal ! my uni professor couldnt be more useless

ycmwwwx

Thanks for suggesting! It's really helpful 😁

I have AB=1ohm, BC=4ohms, CD=5ohms, DA=3ohms and AD=2ohms.

Thank you for your video explanations.
im not goot at neither physics nor english,
but you helped me both !!!! \^-^/

Kirchhoff’s loop rule states that if you travel against the current over a resistor, then +IR and if you travel with the current over a resistor then -IR. So im confused as to how you get the opposite at 4.20 in your video

magnusmeldgaard

Ex1 Rx = 750 ohms Ex2 Rx = 55.5 ohms. Is this corrects? Perhaps you could have showed us the answers on your video😬

Seems to help, let's see if I retain it

When the current flow through the resistor and the current is opposing the loop direction. Shouldn't the voltage drop be positive and not negative.

If R3 doesnt showed/tell any kilo ohms or ohms... How to solve it?

zaidenRYUZAKI

hi. RA is my (RX) whilst my RB is my variable resistor. RC and RD are known. How would I go about calculating this?

WhySoGhostly

high precision Wheatstone bridge are capable to measure the resistance between ?

nitinshikare

ex 1 x=750
ex 2 x=55.5
is it right??

15 goes into 900, 60 times. Missed a 0 in your example. Because 6 times 50 is only 300

Is it ok to arrnge the r1 r2 r3 rx randomly

nsk

Example 1: Rx= 75 ohms, example 2: Rx=55 ohms
