Hi,

Check out this site:

*HINT*

Have you seen Ohm's law V = IR?

If you know the voltage and can measure current with an ammeter, then you can calculate resistance (which measures how "difficult" it is for electrons to flow). The inverse of resistance is conductance, or how "easily" it is for electrons to flow.
