39no , virnag is correct. current decreases in both the cases exponentially.
11no
It has to be p
Reason.
See as the capacitor discharges the voltage is reduced . Reduction in voltage results in reduction of current . Since the voltage drops exponentially therefore current drops exponentially
39i=\frac{q_{0}}{\tau _{c}}e^{\frac{-t}{\tau _{c}}}
this is for 2nd option. so if u draw the i-t graph, u get a exponentially decreasing graph
1d answer key has gievn d answers as
A Q
B P Q
C none (dumbooo)
D R
39well, how can p and q be the answers at the same time? i guess they mistyped current for charge in one of the options and kept the key unchanged.
