Reference no: EM13974975

You are given five light bulbs designed to operate on 160 mA current at 3.0 V (rms values), and want to connect them in parallel, through an ideal transformer, to 120 V rms AC household power.

a) Draw a circuit diagram showing the AC power source (a generator symbol ? ), the transformer, and resistors for the light bulbs.

b) Is the required transformer step-up or step-down? What turns ratio Ns/Np is needed?

c) Calculate the rms current through both the primary and secondary coils of the transformer, in mA.
