notes
... The third term also is caused by a current, but not i1. This is evident by the fact that if we impress a voltage across the primary winding but leave the secondary open circuited (so that i1=(N2/N1)i2=0 because i2=0), we will still be able to measure a voltage across the ...

... The parallel combination yields a resistance of 4 Ω and thus the total resistance is 6.0 Ω. The total current is thus 24 / 6.0 = 4 A. To find the current in the 6 Ω branch, first find the voltage across it, which is the same as the voltage across the parallel combination. This voltage is determined ...
