Capacitor `C_(3)` in the circuit is a 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 to 10 V as `C_(3) rarr oo`. Given that `C_(1) + C_(2) = 10 mu F`

The capacitance of the capacitor `C_(1)` value

Options

A. (a) `2 mu F`
B. (b) `6 mu F`
C. (c) `8 mu F`
D. (d) `4 mu F`

Answer

B
