The geyser draws a heavy current,causing a voltage drop in the supply line.

Vedclass · Answer

(B) When a high-power appliance like a geyser is switched on,it draws a large amount of current from the source.Due to the internal resistance of the supply lines and the source,this high current causes a significant potential drop (voltage drop) across the supply lines.As a result,the voltage available to the bulb decreases momentarily.Since the power consumed by the bulb is given by $P = V^2 / R$,a decrease in voltage $(V)$ leads to a decrease in the power output of the bulb,making it appear dimmer.

$A$ bulb gets dimmer for a moment when a geyser,connected across the same source,is switched on. Why?
