Simulation

The operation of the circuit can be simulated as shown below. During 0 < q < p , the expression for current is presented as equation (9). During p < q < 2p , the expression for current is shown as equation (10).

The voltage across the inductor is obtained to be

vL(q ) = vs(q) - R*i(q) , for 0 < q < p and

vL(q ) = - R*i(q) , for p < q < 2p .

vs(q) = E*sin (q).

It is preferable to normalize vs with respect to E and the current with respect to E/R and then the only value required to be known for solving for the current is t. The applet shown below simulates this circuit. You have to key-in the ratio t and then click on the button next to it. Do not key-in a NaN.
