I just want to make sure I got the right answers for these two questions... 1)If a current of 6A/s in one coil induces a 3V potential in another coil, what is the mutual inductance? I got 0.5 H 2)An ideal transformer connects a 120-V source to a 12-V, 1-A load. The secondary has 90 turns. Determine the number of turns in the primary, which I got 108. And determine the source current which I think is 10A but i'm not sure...

1. What is 6A/s is that supposed to be frequency or what? 2. Unless this is a trick question, you have a voltage step-down transformer 120 to 12 or a 10:1. The primary would have 10 times the number of turns in the secondary. The current would also be 1/10 times the current in the secondary or .1 amp. Note the power is transferred since it is an ideal transformer (120 watts in - 120 watts out)

For the second question i did Npri/Vpri=Nsec/Vsec

Your formula would of resulted in 900 turns also. Check for error.

I thought I would have to change 90 into a decimal (90/100=0.9)

No need, or reason to divide the 90 turns by 100, and remember it is 900 turns (unit is turns)
