Analysis of IV curves: Is the voltage-current relationship different for a light bulb vs. a resistor? The voltage-current relationship for a light bulb in comparison with the resistor is very different in a way that the voltage current relationship for a resistor appears to be linear rather
forming two loops like the IV curve for the light bulb. In addition, a light bulb is like a resistor however it does not have a constant resistance and the resistor results in a voltage drop when it

### 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.
