A blackbox (BB) which may contain a combination of electrical circuit elements (resistor, capacitor or inductor) is connected with other external circuit elements as shown below in the figure (a). After the switch (S) is closed at time t = 0, the current (I) as a function of time (t) is shown in the figure (b).

From this we can infer that the blackbox contains

A

A resistor and a capacitor in series

B

A resistor and a capacitor in parallel

C

A resistor and an inductor in series

D

A resistor and an inductor in parallel

Text Solution

Verified by Experts

The correct Answer is:
