AI Thread Summary
To generate a measurable current through a standard non-uniform clay brick, the required voltage depends on the brick's resistance, which can be in the megaohm range. The user is attempting to determine the resistance by applying voltage across two opposite faces of the brick to achieve a current in milliamps. They are seeking specific information on the resistance of a particular type of clay brick and are encouraged to search online for relevant data. Despite previous attempts at finding this information through Google, they have not had success. Accurate voltage calculations are essential for measuring current in this context.

what sort of voltage would i need to get a measurable current through a standard non uniform clay brick - where the current is in mA?

thanks

In the simplest terms,it would depend on the range in which the resistence of the clay brick is.If it's M\Omega (it's not a metal),then u figure out the voltage...

EDIT:DO NOT DOUBLE POST! :mad:
 
well i am supposed to be working out the resistance by putting a voltage through two oppisite faces of a brick i just need a measurable current so needed an appriopiate electro-motive force (voltage)
does anyone know any where i can find this information or the resistance of a certain type brick?
 
You can google for key words.The name of the substance (whatever that clay is about) and "electrical resistance"...

There have to be some tables out there...

well i tryed google before hand with every variation i could think and have just tryed once again with no success
 

Thread 'Rolling without slipping on a curved surface'

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
