Max power that can be supplied by the source is given by Power=voltage * current.

P(max)=220 * 5 =1100 Watts


It is given that each lamp consumes 30W .

1 lamp - 30W

x lamps-1100W


x comes out to be 36.67

Obviously number of lamps can not be in decimals, therefore round it down

Therefore max number of lamps that can be connected is 36.
