Two heaters rated 220 V / 1 kW and 220 V / 3 kW are connected in parallel across a 220V source. Which of these will heat up faster? Explain why.

Text Solution

Verified by Experts

The heater rated 220V/3 kW heats faster than the heater rated 220 V / 1 kW because branch current across a higher wattage is more than that across a lower wattage.
