Ohm's law states V = IR, Voltage = Current x Resistance. If a toaster has a resistance of 60 ohms and is plugged into a 120 volt outlet, how much current will it "draw"? 5 Amps 2 Amps O 0.5 Amps O 1 Amp
Ohm's Law Name MWITTH Laboratory Report Questions: 1. If the switch were kept closed during the procedures, and the circuit components heated up. how would this effect the measurement of current (D)? Hint, think about how resistance (R) depends on temperature (T) for a carbon resistor. 2. For the rheostat, compute the values of resistance Rh and voltage drop Vh across the rheostat if, Vi-5.0V, the Ammeter reads I-0.056A, and the voltmeter reads Vs-1.69 V.

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,...
