+L=0.225;//inductance in henry

+e=120;//voltage in volts

+f=50;//frequency in c/s

+Xl=(2*%pi*f*L);//inductive reactance in ohms

+mprintf("Inductive reactance in ohms is %2.2f ohms\n",Xl);

+L=0.2;//inductance in henry

+Im=2.4;//peak value of current in A

+//instantaneous voltage equation is e=(sqrt(2)*120*sin(314*t))

+// indefinitely integrating e and later dividing by L we get it as

+//i=-2.4*cos(314t);//instantaneous current in A

+I=Im/(sqrt(2));//in A

+mprintf("Current is %1.3f A\n",I);

+m=(e*sqrt(2)*Im)/2;//maximum power delivered in watts

+mprintf("Maximum power delivered to inductor is %3.2f watts\n",m);

+mprintf("average power is zero\n")

+mprintf("equation for voltage and current are 169.68*sin(314*t) and -2.4*cos(314*t) respectively");
