Question

8.19 Decaying signal The coil in the circuit shown in Fig, 8.32 is known to have an induc- tance of 0.01 henry. When the switch is closed, the oscilloscope sweep is triggered. The 105 ohm resistor is large enough (as you iscover) so that it c parts (a) and (b) of this problem. (a) Determine as well as you can the value of the capacitanceC (b) Estimate the value of the resistance R of the coil. (c) What is the magnitude of the voltage across the oscilloscope input a long time, say 1 second, after the switch has been closed?
