In the absence of an ohmmeter, you have at your disposal a battery, a voltmeter and an ammeter. First, you plug the voltmeter into the battery terminals and measure 10.7V.

Then you cut a 40m piece of wire and connect it in the same way to the battery, with the ammeter in series. The reading is now 3.50A.
