The voltage drop across the resistor is still equal to 10 volts.

Since the rate of current decrease now becomes proportional to the

rate of decrease of E, the output voltage EL remains constant while

ER decreases at a rate equal to the rate of decrease of the applied

voltage.

e. After 60 usec, the applied voltage is equal to zero. EL has

remained constant is equal to 0.5 volt. ER is now equal to EL but

is opposite in polarity. The rate of current change is considered to

remain the same. After 61 usec, therefore, no current is flowing in

the circuit and EL and ER are equal to zero.
