Kush Dawar Phy 2141 9/28/2010 Lab 3: The Relationship between Current and Voltage in Ordinary Solid Matter Introduction: We are trying to understand the relationship between the current and the voltage with the help of ohms law. Plus at the same time we are using different matter in order to change the resistance. We everything goes by plan theoretically we should see a strong positive relationship between the voltage and the current. That is as the current is increasing the voltage is increasing. Purpose: The purpose is to understand the relationship between current and voltage. Basically by observing the current flow with a given voltage in different materials. Procedure Make a series circuit, connect the resistor to the circuit and make sure to connect the volt meter across it. Now record the voltages across the resistor and the current. Now repeat the same process with a resistor (but make sure the resistor is at least over 50) and a filament lamp. After

What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
