Linear and Non-Linear Element Experiment no.2 1.Purpose To experimentally determine the relationship between the current and the potential difference of 3 different devices by studying whether the circuit element obeys Ohm’s law. 2.Data Acquisition and Analysis An apparatus was set to measure the current and voltage (in both current direction) of a resistor, a diode and a light bulb. Figure 1. Circuit diagram Where: R = Resistance (circuit element) A = Ammeter V = Voltmeter S = Switch å = Power Supply A current is said to exist whenever there is a net flow of charge through some region.
