When you connect an unknown resistor across the terminals of a 1.50 V AAA battery having negligible internal resistance, you measure a current of 17.2 mA flowing through it. What is the resistance of this resistor? If you now place the resistor across the terminals of a 12.4 V car battery having no internal resistance, how much current will flow? You now put the resistor across the terminals of an unknown battery of negligible internal resistance and measure a current of \(0.451\) A...

The voltage drop (V) across a resister is proportional to the current (I) through the resister. Ohm's Law: V = IR. Wednesday's laboratory expernnent attempts to verify Ohm's Law and measure the resistance (R) of a resister Ammeters and voltmeters potentially have offsets, resulting in a constant added to the equation: V = IR + VO If voltage satisfying this equation is plotted against current, the result is a line. With voltage on the y-axis and current on the r-axis,...
