Unformatted text preview: How does one calculate the capacitance for different conductor geometries? Do 3018(pe), 3056(pe). 4. How do capacitors in series and parallel add? Do 3020(wb), 62(pe). 5. How does one calculate the energy of a capacitor? And where is a capacitor’s energy stored? Do 3021(wb), 3031(pe). 6. What is an electrical current? Do 311(1e), 4(wb). See below for the (1e) problem. 7. What is conservation of electrical current? Do 319(wb), 10(wb). 8. What is the distinction between an electrical current ‘i' and an electrical current density ‘j’? Do 3113(wb), 17(wb). 9. What does Ohm’s Law tell us about the relationship between electric potential difference and electrical current in normal conductors? Do 3125(wb), 35 (pe). Problem 311(1e): 1.0 x 10 20 electrons flow through a cross section of a copper wire each second. The wire is 2.0 mm in diameter. (a) Calculate the electron driftspeed in the copper. (b) Calculate the electrical current through the wire....
