Small transformers that power products

[lisanoir]

Homework Statement

the smal transformers that power many consumer products produce a 12.0Vrms, 60hz EMF. design a circuit using resistor and capacitors that uses the transformer described above as an input and produces 6.0 Vrms output that leads the input voltage by 45 °

Homework Equations

BACOSθ=BA COSωt
wt=90° or 270° for it to have maximum magnetic field in the plane of the coil
Emax=NABω
E=-N d/dt∅b= -NABd/dt(cosωt)

The Attempt at a Solution

ΔVrms=12.0v-6.0v= 6.0Vrms

as a loop rotates in a magnetic field, the magnetic flux through the area enclosed by the loop changes with time ad therefore, induces an emf and current in the loop

The problem says to add Rs and Cs to the existing transformer to obtain the smaller, phase shifted output waveform. It looks like you are describing some sort of motor topology?
