Section: 7 Date: 25/2/2005 Instructor: Dr. Ziyad Izzat 1) The aim of this experiment is to check whether the electronic elements involved in this experiment are linear or non-linear conductors. 2) The method used is direct measurements of: Voltage (potential difference) and electrical current through those components, then doing the proper calculations and comparisons. 3) The main result is : The resistor is a linear component, whereas the diode and the light bulb aren’t. = 176 R 1 Theory: I-V characteristic is the relation between the current passing through a circuit component and the voltage difference between its terminals. And when such a relation is plotted; components that have a straight line I-V characteristic are called linear components 2 . And the slope of this representative graph is the value (1/resistance) of the component. And since linear components’ graphs are straight lines, then this value is a constant and so is the 1 R is the resistance of the resistor. 2 They are also called ohmic components for a reason that will be mentioned later.
value of the resistance. However, most resistors used in laboratory are linear carbon resistors. 3 On the other hand, components that don’t posses straight line I-V characteristics are called non-linear components. And example is a diode; a device frequently used in electronic circuits to provide on way current
