Use the 'applet on Ohm's law to review the experiments. Close
blue switch dragging with your mouse.
Do this: fixed resistance R, then the potential difference varies G. Sull'amperometro read the intensity of current flowing in the circuit.
eg with R = 10 ohms, and G = 5 volts, the current is 0.5 amps.
Prepare a table with the values \u200b\u200bof G in volts and current I in amperes and build the graph. Another
link where you can, set the resistance (note the colors have a code that lets you know the value), varying the voltage, current sull'amperometro read: build the chart and make your comments.
