Assignment:
Question 1. How would you arrange two flat circular coils so that their mutual inductance was a) greatest b) least (without separating them by a great distance)?
Question 2. If you are given a wire of such length that you can make only two loops out of it, how would you shape this wire to obtain a) the greatest; b) the least self-inductance?
Question 3. What is the inductance L of the primary of a transformer whose input is 220 V at 60 Hz and the current drawn is 5.8A? Assume no current in the secondary.
Provide complete and step by step solution for the question and show calculations and use formulas.
