A) The strater motor draws a larger current resulting in a larger potential drop in the battery which reduces the terminal voltage of the battery
B) When the strater motor is switched on, it increases the resistance of the filament of the bulb in the car light
C) When the strater motor is switched on \[j\] reduces the EMF of the battery
D) none of these
Correct Answer: A
Solution :
This is like dimming of a tube light when a geyser or motor is switched on in household circuit. When starter motor is switched on (in parallel), \[{{R}_{eq}}\]decreases, current supplied increases, the drop across the internal resistance\[(I\,\,r)\]. increases, the remaining voltage across the parallel branches \[(E-Ir)\]decreases. So, the power across the parallel branches\[\frac{{{V}^{2}}}{R}\]decreases.
