A combination of 
capacitor with an initial voltage 
in series with a 
resistor is connected to a 20mA ideal dc current source by operating both switches at t = 0 s as shown. Which of the following graphs shown in the options approximates the voltage 
across the current source over the next few seconds?
Explanation:
Switch across current source is opened at t = 0
Since, Voltage across capacitor cannot change instantaneously
For t > 0
= 
So, curve is a straight line passing through origin as shown.
