Describe Ohm’s Law (virtual lab session).

Our experimental setup consists of a one-loop electric circuit, made of a DC power source (12 V), a variable resistor with 6 positions (0, 2, 4, 6, 8, and 10), and a small light bulb. Potential differences and electric current intensities are measured at different points of the circuit, using standard voltmeters and ammeters. Experimental data is then annalized in order to validate Ohm’s law, and discuss its limitations.
