Homework Help Overview

The discussion revolves around determining the voltage required to generate a measurable current through a standard non-uniform clay brick, specifically aiming for current levels in milliamperes. The subject area includes concepts of electrical resistance and voltage in non-metallic materials.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • Participants explore the relationship between voltage and resistance in clay bricks, questioning what voltage is necessary to achieve a measurable current. There are attempts to identify the resistance of the clay brick and how it influences the required voltage.

Discussion Status

The discussion is ongoing, with participants sharing insights about the resistance of clay bricks and suggesting that further research may be needed to find specific resistance values. Some guidance is offered regarding searching for information online, but there is no explicit consensus on the voltage needed.

Contextual Notes

Participants mention constraints such as the non-metallic nature of clay bricks and the variability in their resistance, which complicates the determination of the necessary voltage. There is also an indication of frustration with the availability of information on this topic.

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 resistance of the clay brick is.If it's [itex]M\Omega[/itex] (it's not a metal),then u figure out the voltage...

Daniel.

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...

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