If a high power heater is connected to electric mains, then the bulbs in the house become dim, because there is a

Two wires ‘A’ and ‘B’ of the same material have their lengths in the ratio 1: 2 and radii in the ratio 2: 1. The two wires are connected in parallel across a battery. The ratio of the heat produced in ‘A’ to the heat produced in ‘B’ for the same time is
