Capacitor `C_(3)` in the circuit is variable capacitor (its capacitance can be varied). Graph is plotted between potential difference `V_(1)` (across capacitor `C_(1)`) versus `C_(3)`. Electric potential `V_(1)` approaches on asymptote of 10 volts as `C_(3) to infty` The value of C3 for which potential difference across `C_(1)` will become 8V, isA. `2 mu F`B. `6 mu F`C. `8 mu F`D. `4 mu F` |
