The figure below shows the circuit from Example 11.9-1 of

The coupling coefficient must satisfy .

The steady state response of this circuit is given by

The values of the inductances L_{1} and L_{2} of the coupling coefficient k can be changed using the scrollbars. Notice that the circuit diagram is labeled using the value of the mutual inductance M calculated from L_{1}, L_{2} and k.

Suggestions:

- Set L
_{1}=4 H, L_{2}= 3 H and k=0.58 to see the circuit in**Example 11.9-1**. - Set L
_{1}=6 H, L_{2}= 8 H and vary k. Watch M change as k changes. What is the range of values of M corresponding to ? Predict the value of k required to obtain M=6 H. Use the scrollbars to check this prediction. - Set L
_{1}=9 H, k = 1 and vary L_{2}. Watch M change as L_{2}changes. What is the range of values of M corresponding to ? Predict the value of L_{2}required to obtain M=8 H. Use the scrollbars to check this prediction. - Use the scrollbars to select values of L
_{1}, L_{2}and k such that . Verify the values of L_{1}, L_{2}and k using the given equations.
