| you and a friend are contestants on the now famous show \"junkyard wars.\" as part of the machine you decide to build, you have an alternating current motor with a voltage requirement of 120 volts but there is no outlet around-- you are in the middle of a junkyard. you only have a 220 volt power supply that supplies 1 amp, so you need to use a transformer to \"step down\" the voltage. your friend finds a transformer that has about 1000 winds on the input side, but the output side has been stripped. How many winds do you need to put on the output side to step the voltage down to the 120 volts you need?
