(B) When a high-power heater is connected to the electric mains,it draws a large amount of current from the source. Due to the internal resistance of the supply lines (wires),a significant voltage drop occurs across these lines according to Ohm's law,$V = IR$. As a result,the effective potential difference available across the bulbs decreases. Since the brightness of a bulb is proportional to the square of the voltage $(P = V^2/R)$,a decrease in the potential difference leads to a reduction in the power consumed by the bulbs,causing them to become dim.

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