Question

Lost in the wilderness, you have a signal beacon that runs on 9.0 volt batteries. Unfortunately, the battery you packed it with has died, and all you have is a single 1.5-volt AA battery. You tear apart the other electronic equipment in your gear and use the parts to create a working step-up transformer. Questions:

•if the voltage is to be stepped up from 1.5 volts to 9.0 volts, what should the turns ratio be? why?

•assuming the turns ratio is correct, will the transformer work with a battery supplying the power? why or why not?

Explanation / Answer

(a) Transformer ratio :    Ns / Np = Vs / Vp                   = 9 volt / 1.5 volt                 = 6     (which is > 1 ,thus, trans former is stepup ) where s ,p indicates the secondary , frimary ciol    in the trnasformer (b) yes, transformer work with a battery supplying the power since ,secondary voltage is 6 times the primary ciol
