Kettle Efficiency Ratings At Amanda Edmondson Blog Explore the energy conversion efficiency of electric kettles through a detailed lab experiment measuring temperature changes and energy consumption. In this experiment, the thermal efficiency of a conventional kettle using an insulation hood developed and 3d printed by me with a 20 mm armaflex insulation is investigated. Questions: 1.how much electrical energy was used by the kettle? 2.how much heat energy was absorbed by the water? 3.what is the efficiency of the kettle? 4.where did the rest of the energy go? 5. draw a sankey diagram into your copybooks. Q. what do you mean by the heating efficiency of an electric kettle with varying voltages? ans. to find the dependence of rise in temperature of a given mass of water in a given time interval on the voltage at which the electric kettle works.

Q. what do you mean by the heating efficiency of an electric kettle with varying voltages? ans. to find the dependence of rise in temperature of a given mass of water in a given time interval on the voltage at which the electric kettle works. 1 experiment : to study heating efficiency of an electric kettle using voltage variation fixed voltage. apparatus and materials: 1. electric kettle 2. measuring cylinder (or beaker) 3. thermometer 4. stopwatch 5. weighing balance (optional, if measuring mass of water) 6. multimeter (if power rating needs verification) theory: formula used:. The power rating of an electric kettle tells us how many joules of energy are transferred in the heating element every second. so an electric kettle with a power rating of 3 kw transfers 3000 joules (3 kj) of energy every second. Use your data from the experiment in equation (6) to find the energy losses during boiling of your kettle by substituting your measured values of the mass of water, m temperature change t and electrical work, win used during the boiling process. The experiment is repeated using a number of optical filters and the corresponding values of the stopping potentials are found. a graph is drawn between the known frequencies and corresponding stopping potential.
