Question

1.The war of the currents in the 1880's involved Thomas Edison and Nikola Tesla on a reality TV show stranded on an island. Each had to construct a current generating device out of the local floral and fauna. After 3 seasons, Nikola Tesla won and Thomas Edison was voted off of the Island.

True

False

2.

Transformers are the reason wall outlets operate at AC.

True

False

3.

Transformers will work at DC.

True

False

4.

What are the ideal transformer assumptions that are only true for the ideal case and not true for a real device?

All of the magnetic flux passes through both coils.

The transformer is lossless

The self inductance of each coil is infinite

The current in the primary winding will produce a magnetic field.

Time varying magnetic fields passing through a coil of wire will induce a voltage.

Explanation / Answer

1). War of current is the fight between ac current and dc. the ac current is invented by tesla. and it is not the reality show.

2). Transformer works at ac only. because emf generated by rate of change in magnetic field. TRue

3).false.
