Resistors and Ohms Law - Voltage-Current Characteristics

Setting ups for measuring Voltage and Current.



Data we have acquired. (3V is at last)
Table and graph. (Equation of the regression line is y=0.0105x-0.0021)
Summary: The Voltage and resistance across resistor change with changing in Voltage source. Unlike ideal condition V=IR. However, it does not varies significantly. This happends because there are no or little such thing as ideal voltage source. Voltage across poles changes with respect to resistors. (I think so) 

Additionally, we did some other problems, like this one. (We gave Voltage sources polarities and got our current and used it solve for voltage across point A to B.)
