Unformatted text preview: CLASS PROBLEM: If a D‐cell battery supplies 2W of power to a small bulb, then find (a) the current through the bulb, and (b) the resistance of the bulb. CLASS PROBLEM: Consider the circuit depicted below. (a) What is the total current supplied to the resistors (the current that leaves the power source)? (b) How much power is consumed by the resistors? TIPS: 1. Combine adjacent series resistors. 2. Compute the equivalent resistance of each “bank” of parallel resistors. 3. Repeat steps 1 and 2 above until Req is found. ...

### 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.
