An electric circuit is set up in such a way that the positive terminal of a battery V is connected to a bulb `B_(1)` which is connected to a resistor R which is connected to bulb `B_(2). B_(2)` is finally connected to the negative terminal of the battery. Both the bulbs are glowing. If the value of R is increased, then

Options

A. Both `B_(1)` and `B_(2)` will become dimmer
B. `B_(1)` will become dimmer but brightness of `B_(2)` will remain unchanged
C. `B_(2)` will become dimmer but brightness of `B_(1)` will remain unchanged
D. Both `B_(1) and B_(2)` will remain unchanged

Answer

A
