In the circuit shown, [JEE Main 11-Jan-2019 Morning] |
the switch \[{{S}_{1}}\] is closed at time t = 0 and the switch\[{{S}_{1}}\]is opened and \[{{S}_{2}}\] is closed. The behavior of the current I as a function of time t is given by |
A)
B)
C)
D)
Correct Answer: A
Solution :
[a]: Initially, when the switchis closed the current increases and when the switch is closed the current starts decreasing exponentially i.e., according to . |
So, the behaviour of the current can be depicted from the following graph: |
*As per official answer key. |
Value is not specified hence a, b and c may be correct option. |
