The fan converts electric energy into kinetic energy that does work, and it converts some electric energy into heat.)
What energy transformation takes place in dry cell and electric fan?
1) in dry cell – chemical energy is converted to electrical energy. 2) In electric fan – electrical energy is converted to mechanical energy and wind energy .
What is the main energy transformation that occurs in i working of a fan 2 a microphone?
(iv) Microphone: Sound into electrical energy.
What is one of the most common energy conversions?
The most common energy conversion is the conversion between potential and kinetic energy. Kinetic Energy is the energy of motion. Potential Energy is stored energy. The energy of motion is called kinetic energy.
What are the 3 energy transformations?
Battery (electricity) (Chemical energy → Electrical energy) Fire (Chemical energy → Heat and Light)
What kind of energy transformation takes place in a human body?
Answer: When a body falls, its potential energy gradually gets converted into kinetic energy. On reaching the ground, the whole of the potential energy of the body gets converted into kinetic energy.
What are examples of energy transformation?
What are some examples of energy transformation?
- The Sun transforms nuclear energy into heat and light energy.
- Our bodies convert chemical energy in our food into mechanical energy for us to move.
- An electric fan transforms electrical energy into kinetic energy.
How is electrical energy transformed heat?
Electric heating is any process in which electrical energy is converted to heat. … The heating element inside every electric heater is simply an electrical resistor, and works on the principle of Joule heating: an electric current through a resistor converts electrical energy into heat energy.
What is the best example of a device that converts electrical energy ⇒ thermal energy?
Examples of Electrical Energy to Thermal Energy Conversions: 1. A toaster draws electric current (electrical energy) from a wall outlet and converts these moving electric charges into heat (thermal energy) in the filaments that turn red hot to cook your toast.
What appliances transfer electrical energy into heat?
An electric fire, a cooker, a toaster and an electric kettle all convert electrical energy into heat energy. The power of an appliance is the rate at which energy is transferred.
