The resistance of an electric stove element at operating temperature is 11 \Omega
1. If 220 V are applied across it, what is the current during the stove element?
2. How much energy does the element convert to thermal energy in 30.0 s?
3. The element is being utilized to heat a kettle containing 1.20 kg of water. Suppose that 70 percent of the heat is absorbed by the water. What is its increase in temperature during the 30.0 s?
