Final Answer : 40
Steps :
1) Total Potential difference generated across the ends of the wire is 240 V.
2) Characteristic Voltage drop across each bulb will be 6V.
Assuming Ideal case in which there is negligible resistance due to wire.
=> Maximum no. of LEDs required which can be set across. given potential gap
is 240/6 = 40 .
