What is the disadvantage of heat application?
Following are the disadvantages of the heating effect of current: 1) When an electric current flows through the conductor, a part of it is converted into heat energy. This is a waste of energy. 4) An additional cooling system needs to be added to the circuit to counter the heating effect.
What is heat engine and its efficiency?
Heat engine is a device that performs the conversion of heat energy to mechanical work through cyclic process. The efficiency of a heat engine is defined as the ratio of work done by the heat engine to heat absorbed per cycle.
Why is heat engine not 100 efficient?
A heat engine is considered to be 100% efficient if only all the heat is converted into useful work or mechanical energy. Since heat engines cannot convert all the heat energy into mechanical energy, their efficiency can never be 100%.
What are the characteristics of heat engine?
Key qualitative points are: (1) loop shape; (2) maximum efficiency being far below Car- not efficiency; (3) proximity of maximum efficiency and maximum power points. deterrent to operating at both high and low rates of heat input.
What are the disadvantages and advantages of heating effect of current?
1) When an electrical current flows through the conductor, a neighborhood of it’s converted into heat. This is often a waste of energy. 2) the warmth produced can damage the insulation and other electrical components, or maybe cause a fireplace. 3) Reduces the lifetime of several components within the circuit.
What are some advantages and disadvantages of biomass energy?
