E I A B S C Three identical that is same resistance lamps A B C are connected to a battery as shown The resistance of the switch S is negligible With the switch S initially op the brightness of that is the power delivered to bulb A is 27 29 W Watts After S is closed this means that the potential difference across the switch vanishes the brightness of the bulb A in W is
