i1 R1 = i2 R2
and R1 = rho l/A
R2 = rho 30l/A
and no I won't do your homework for you.
There is current of 115 pA when a certain potential is applied across a certain resistor. When that same potential is applied across a resistor made of the identical material but 30 times longer, the current is 0.044 pA. Compare the effective diameters of the two resistors.
d2/d1 is the units in the last answer.
