Three bulbs `B_(1), B_(2) and B_(3)` are connected to the mains as shown in Fig. `7.28`. How will the brightness of bulb `B_(1)` be affected `B_(2) or B_(3)` are disconnected from the circuit?

Three identical bulbs B_(1),B_(2) and B_(3) are connected to the mains as shown in figure. If B_(3) is disconnected for the from the circuit by opening switch S, then incandescence of bulb B_(1) will . ,
