A well-insulated electric water heater warms 137 kg of water from 20°C to 45.0°C in 16.0 min. Find the resistance of its heating element, which is connected across 220-V potential difference.
The Attempt at a Solution
Not sure how to approach this one. Should I refer to a calorimetry approach along with electrical relations? How might I start this one?
Any help/hints would be greatly appreciated.
