In an LCR circuit as shown below both switches are open initially. Now switch\[{{S}_{1}}\]is closed, \[{{S}_{2}}\] kept open. (q is charge on the capacitor and\[\tau =RC\]is Capacitive time constant). Which of the following statements is correct? |
| A. | At, t=0, q=CV (1-e) |
| B. | At,\[t=\tau \], \[q=CV/2\] |
| C. | At, \[t=2\tau \], \[q=CV(1-{{e}^{-e}})\] |
| D. | At, \[t=2\tau \], \[q=CV(1-{{e}^{-1}})\] |
| Answer» D. At, \[t=2\tau \], \[q=CV(1-{{e}^{-1}})\] | |
