Solution:
(i) When only bulb is ON,
(ii) When geyser is also switched ON, equivalent resistance of bulb and geyser is
Voltage across the bulb,
Hence, the potential drop is
The wiring of a house has resistance 6 Ω. A 100 W bulb is glowing. If a geyser of 1000 W is switched on, the change in potential drop across the bulb is nearly (Supply voltage is 220 V)
