with the 100 centimeters of No. 30 German silver wire as shown in the diagram. The ammeter gives the current in amperes passing through the wire, and the voltmeter gives the fall of potential in volts. Read the amperes and volts to tenths. Be careful to leave the battery connected only long enough… … In like manner determine the resistance of 50 centi-meters of the German silver No. 30 and compare itwith the resistance of 100 centimeters of the samewire to show the effect of length. To show the effect of diameter, determine theresistance of 100 centimeters of German silver No. 24and compare it…
