Purpose: Purpose: One of the most frequently applied relationship in current electricity is that known as Ohm's law. This relationship is fundamental to the analysis of clectrical circuits. It relates to the voltage (V) and current (I) associated with a resistance (R). In this experiment, Ohm's law will be investigated as applied to components in a simple circuit. After performing this experiment and analyzing the data, we should be able to: Distinguish between ohmic and nonohmic resistances. Explain current-voltage relationships by Ohm's law. Apply Olim's law to obtain values of current or voltage in investigating a circuit resistance. . Theory: When a voltage or potential difference (V) is applied across a material, the current (I) in the material is found to be proportional to the voltage I V. The resistance (R) of the material is defined as the ratio of the applied voltage and the resulting current- that is. R= For many materials, the resistance is constant, or at least approximately so, over a range of voltages. A resistor that has constant resistance is said to obey Ohm's law or be "ohmic". Ohm's law is said to be “nonolmic" and have a nonlinear voltage-current relationship. Semiconductors and transistors are nonohmic. In common practice. Ohm's law is written V = IR Where it's understood that R is independent of V.
