look atface area.
largest area: 6cm^2 length: 1cm
Minimum area: 2cm^2 length 3 cm
current will be in proportion to 1/resistance which is proportional to length/area, current=constant*area/length
Min current, max resistance
1mA=constant(2/3)
currentmax=constant(6/1)
constant=1mA*3/2
currentmax=1mA*3/2*6/1=9mA
A rectangular conducting homogeneous (which means the material is the same throughout) block has dimensions 1cm×2cm×3cm . A voltage V is applied between all opposite faces of the block and the corresponding currents were recorded. What is the maximum current measured in Amps if the minimum current recorded is 1mA.
