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
