Question

The secondary of the Transformer is open-circuited(see attachment).Calculate the secondary voltage V2 if V1=sin10t,L1=0.8H,L2=0.4H and M=0.2H(M-mutual inductance)?

Answer 1

well, first note that \[\omega =10rad/\sec\]

Answer 2

\[XL = j \omega L\]

Answer 3

convert all of the circuit into the phasor domain

so 0.8H ---> 8j

0.4H ---> 4j


M= 0.2H ----> 2j

Answer 4

not sure what to do now :| , havent seen questions where one loop is open circuited, the only question I have seen is where there are two complete meshes on both sides
