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 [itex] M\Omega[/itex] (it's not a metal),then u figure out the voltage...

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...
