Heat pumps are extremely energy efficient. With the knowntonnage(or BTUs), theSEER rating, and theHSPF rating, we can calculate almost exactly how much electricity a heat pump use (watts, kWh usage)per hour,per day, and evenper month. Based on that, we can calculate how much it costs ...
Hydroelectric power produces electricity using Explain the energy transformation processes in an electromagnet. How are energy, work and power related? How can a magnetic field be produced around a wire? What principle do Tesla coils use to generate electricity?
In a petrol-powered car, the engine produces a great deal of waste heat, which is then used to warm the interior efficiently when needed. By comparison, the electric motor and battery in an electric car produce less waste heat; this is why a heat pump is required. ...

This new technology has the potential to make a big difference in many areas. Industries such as manufacturing, which produce large amounts of leftover heat, could see major benefits by turning that waste heat into electricity. This would help them save energy and lessen their impact on the ...
The high temperature also has an advantage: The steam that the fuel cells produce can be channeled into turbines to generate more electricity. This process is called co-generation of heat and power (CHP) and it improves the overall efficiency of the system. Alkaline Fuel Cell (AFC) This is...
Find the heat produced in joule if a current of 0.1 A is passed through a coil of resistance 50Ωfor two minutes. Keeping other conditions the same if the length of the wire is reduced to14th the original length ( by cutting the wire), what will be the heat produced ?
Electricity flowing into the transmitter antenna makes electrons vibrate up and down it, producing radio waves. 2) The radio waves travel through the air at the speed of light. 3) When the waves arrive at the receiver antenna, they make electrons vibrate inside it. This produces an electric ...
