Two similar bulbs of wattage `100 W//50 sqrt(2)V` are connected in circuit as shown when frequency of source is varies, brightness of `B_(2)` changes it is observed that at 50 Hz frequency both the bulbs have same brightness. Select correct alternative/s
A. Current in both the bulbs wil be in same phase when both have same brightness
B. Current through source will be 2A when both the bulbs have same brightness
C. Current through source will be `2 sqrt(2)A` when both the bulbs have same brightness
D. `B_(1)` will be more brighter for all frequencies axcept 50 Hz
