Another physics question that has to do with transformers?

A doorbell requires 0.4A at 6 volts. It is connected to a transformer whose primary contains 2000 turns and is connected to 110 volts household current.



a) How many turns should be in the secondary?



b) What is the current in the primary?



c) Is this a step-up or step-down transformer?Another physics question that has to do with transformers?a) The turns ratio will need to be;



110v primary / 6v secondary = 18.3



2000 turns primary / 18.3 = 109 turns secondary



b) 0.4A secondary / 18.3 = 0.022A primary



c) primary voltage is higher than secondary voltage - step down transformerAnother physics question that has to do with transformers?you're probably thinking bumble bee. but it's actually optimus prime
