    The reason for this is that when we swich on heater then current coming to our house increase ,therefore V =e.mf_ir Where,v=potential difference, i=current &r=i nternal resistance According to above relation ,, When i (current )increase ,v (potential difference decreases. Hence, thete is dim in brightness of bulb due to decrease in potential difference.
