Simple but fundamental electrical calculations for resistance are reviewed witha view to their application in studies of plant tissue. The relationship of re颅sistance to ion mobility, to temperature, to specific resistance, and to complextissue is discussed. It would appear that the specific ...
This relationship is also called Ohm’s law. Ohm’s law in this form really defines resistance for certain materials. Ohm’s law (like Hooke’s law) is not universally valid. The many substances for which Ohm’s law holds are calledohmic. These include good conductors like copper and alumi...
Georg Simon Ohm, 1787--1854 Here is a circuit diagram. ag1:close the switch Trim up to change the resistance of R2(the sliding rheostat) Can you find out the relationship between current and voltage of R1(the fixed value resistance) by changing the resistance of R2? Can you work out th...
