WebElectrical Engineering questions and answers. 12. In Experiment 6, a fixed resistor was in series with a variable resistor. You plotted the resistance of the variable resistor as a function of the power dissipated in it. What would you expect the graph to look like if the fixed resistor were a lower value? WebSep 22, 2024 · Variable Resistor Characteristics. The most important characteristic of a variable resistor is given by the relation between the mechanical position of the moving terminal and the resistance ratio. It is …
WebJan 2, 2010 · Plot a graph of average current against voltage (an I–V graph) for each component; If the I–V graph is a straight line, it is an ohmic conductor. This is expected from the fixed resistor. This means it obeys Ohm's Law: V = IR; If the I–V graph is a curve, it is a non-ohmic conductor. This is expected from the filament lamp and diode
