  1. much too many

    10. I = E/R = 120/4 = 30 amps

    9. second

    8. Kir's current law

    7. 100/R = 100/15 + 100/35 + 100/65

      100/R = 6.67 + 2.86 + 1.54 = 11.07

    R = 100/11.07 = 9.03 ohms


  2. 1) same

    2)low, high

    3)resistance

    ........

    pay me for da rest :P
