220v, 10w, and 1 10v, 10w, which two appliances generate more heat in the same circuit?
There is no such formula, because the power of these appliances is the same, and the electric energy consumed at the same time is the same, while TV sets need to convert electric energy into light energy and vibration (sound), electric fans need to convert electric energy into kinetic energy (fan rotation), and only electric soldering irons only convert electric energy into heat energy, so natural electric soldering irons generate the most heat energy.
I know that formula. Let me talk about my humble opinion, P=UI, U=IR, so P = I 2r, energy = Pt = I 2rt, but this formula is based on U=IR. But if it is other electrical appliances, U=IR may not be established. Remember that resistance only holds in some cases, so don't use this formula unless it is pure resistance.
