NEET MCQ Books for XIth & XIIth Physics, Chemistry & BiologyA 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 figure (a). After the switch is closed at time \(t=0,\), the current \((I)\) as a function of time \((t)\) is shown in figure (b).
From this, we can infer that the Blackbox contains:
| 1. | a resistor and a capacitor in series. |
| 2. | a resistor and a capacitor in parallel. |
| 3. | a resistor and an inductor in series. |
| 4. | a resistor and an inductor in parallel. |
