HWK 39 (SOLUTIONS) (due 4/30/07) Read chp. 37 sections 5-6 Do 13, 16, 17(a and b), 37 13. A transformer transforms energy from P.E. to K.E. or vice-versa. A step down transformer transforms potential energy to kinetic energy. We go from high voltage/low current to low voltage/high current. (Remember how in gravity, high P.E. is at higher ele- vation? So think about stepping down to lower potential energy with a step down transformer.) A step up transformer trnasforms kinetic energy to potential en- ergy. We go from low voltage/high current to high voltage/low current. You can think about ”stepping up” to higher potential energy. Note: It is not voltage or current that is being transformed here. Al- though voltage is connected to potential energy and current is con- nected to kinetic energy, it is energy itself that is being transformed one type to another. 16. In a transformer, the secondary coil has ten times more turns than the primary coil. The input voltage to the primary coil is 6
