EE10 Winter 2008 Homework 1 Assigned: Jan 11 Due in Class: Jan 18 1. A double sided 3 ½” floppy disk holds 1.4MB. The bits of data are stored on circular tracks, with 77 tracks per side. The radius of the inner track is ½”, while the radius of the outermost track is 1 ½” . The number of bits per track is the same, and there are 8 bits per byte. How much area does a bit stored on the innermost track occupy, in square micrometers? 2. Four 1.5V batteries supply 100mA to a portable CD player. How much energy do the batteries supply in 3 h? 3. Two electric circuits, represented by boxes A and B, are connected as shown in the figure. The reference direction for the current i in the interconnection and the reference polarity for the volt- age v for the interconnection are as shown in the figure. For each of the following sets of numeri- cal values, calculate the power in the interconnection and state whether power is flowing from A to B or vice versa.

### 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.
