A room is lighted by 200W, 124V incandescent lamps fed by a genrator whose output voltage is 130V. The connecting wires from the generator to the user are made of aluminium wire of total length 130V and cross-sectional area 15`mm^(2)`. How many such lamps can be installed? What is the total power consumed by the user?Specific resistance of aluminium `=2.9xx10^(-8)Omega`m.
