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.
