Unformatted text preview: inductor. 2. After the abovediscussed steady state is reached, the switch is opened. What will be the voltage across the inductor just after the switch is opened? (Hint: much to the disappointment of many of you, there will be no sparks because R 2 is present.) 3. For the case when the switch has just been closed, label the currents in the three twoterminal elements I L , I 1 , I 2 . Write Kirchoff’s current law for the junction of R 1 , R 2 , and L. Write Kirchoff’s voltage law for the loop including the battery, R 1 and R 2 . Relate the voltage across the inductor to the voltage across R2. 4. (Bonus) Combine the above to write a single differential equation for the current in the inductor....
