ECE 210 Section 1 (week beginning 1/7/2011) 1/ Power, Energy, and Ohm's Law (No Prelab) 1. The rating on a 12 V car battery is 100 ampere hours (for example, it will provide I amp for 100 hours or 100 amps for I hour). Assuming the voltage remains at 12 V during a discharge of the battery, how much energy is stored in the battery?

### 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.
