Unformatted text preview: Alycia Suber PHYS 2120 Dr. Wang June 7, 2010 Lab partners- Anjnea G., LaToya W., Gabrielle G., Donell W. Laboratory 03 – DC Circuits Purpose In this experiment, measurements of the voltage and current across a resistor and the resistors will be used to demonstrate the equivalent resistance of resistors in series and in parallel arrangements. Equipment List 1. Five resistors range from 100Ω to 1000Ω 2. Ammeter (Direct Current) 3. Voltemeter (direct current, preferably digital readout-digital multimeter) 4. Direct-current power supply (0-30V) 5. Breadboard Theory If a potential difference V is applied across some element in an electrical circuit, the current I in the element is determined by a quantity known as the resistance R. the relationship between these three quantities serves as a definition of the quantity resistance. Other circuit elements may have other important electrical characteristics in addition to resistance such as capacitance or inductance. The resistance of any circuit element, whether it has other significant electrical properties or not, is given by...
