This process will continue until C is completely discharged (tank is empty) and the voltage is 0 (pressure is 0).
Initially, the voltage (pressure) was high and the rate of discharge (draining) was rapid. As the voltage (pressure)
decreased, the rate of discharge (draining) decreased.
In any RC circuit, when the capacitor is discharging, the voltage across R is the same as the voltage on C.
No
answer 76.
The capacitor in fig. 10 was charged to 180 volts with the switch in Pos. A. The
required
switch is now moved to Pos. B.
Figure 10.
At the end of 1 RC time, the voltage on the capacitor (EC) has decreased
by
%.
At 1 RC time, EC =
volts.

77.
Referring to fig. 10, at 1 RC time, ER =
volts. (Hint-when C is
66.6
discharging, ER = EC.)
