SUMMARY
The discussion focuses on calculating the power absorbed by a heater rated at 2000 W operating at 250 V when supplied with 230 V. The resistance of the heater is determined to be 31.25 Ω using the formula R = V²/P. The power absorbed by the heater at the lower voltage is calculated to be 1692.8 W using the formula P' = V²/R. The calculation confirms that the heater operates efficiently despite the voltage difference.
