What energy transformation occurs in the electric iron?
Which energy transformation occurs in an electric iron
What form of energy is produced by Hydro?
Electrical energy produced from mechanical energy (kinetic energy) that moving turbines.
Could Electrical energy be produced from mechanical energy?
Yes. All power stations do that.
What energy transformation takes place when an electric drill is used?
Electricity is turned into mechanical rotation.Some of the rotation removes material from the hole while some becomes heat energy.assuming the electric drill has no monitors and has just a drill, and assuming the electric drill is powered by rechargeable lithium ion batteries, things happen in the order below starting with the drill battery charger1. drill charger converts electrical energy into chemical energy and stores it into the lithium ion battery2. when the user pushes the power button of the drill, chemical energy of the lithium ion battery is converted into electrical energy3. the electrical energy is converted into magnetic energy by the coil in the drill motor4. the magnetic energy then converts into kinetic energy and spins the drill head5. when the drill head touches something, part of the kinetic energy is converted into sound energy which we hear, thermal energy is also created when the drill touches something, which is caused by friction
What 2 ways that electrical charge can be produced?
Generator (mechanical device), batteries (chemical device).
How does a generator convert mechanical energy into electrical energy?
An electric generator is a device used to convert mechanical energy into electrical energy, Which is used to convert mechanical energy into electrical energy. The generator is based on the principle of "electromagnetic induction" discovered in 1831 by Michael Faraday, a British scientist. Faraday discovered that if an electric conductor, like a copper wire, is moved through a magnetic field, electric current will flow (be induced) in the conductor. So the mechanical energy of the moving wire is converted into the electric energy of the current that flows in the wire.
How does electrical energy change to sound energy?
Electrical energy to sound energyExampleSpeakerA coil of wire(voice coil) is placed (inside the cone) in magnetic field produced by a strong permanent magnet, the signal to converted is applied to the coil, so a magntic field is produced due to electric current in the coil. The coil system and permanent magnetic field interacts, so mechanical motion is produced and it causes the coil to move to&fro and it touches the cone, therby reproducing sound from the electrical signal..
What form mof energy is produced in an electric fan?

What form of energy is produced in a radio?
kinetic converted to electrical.
Which Device converts electrical energy from mechanical energy?
Modern electrical generators make use of Faraday's law to convert mechanical energy in the form of motion into electrical energy. Mechanical energy is used to turn large magnetic coiled in electrical wire, and as the magnets and thus magnetic field moves, an electrical current is induced in the wire producing electricity. The actual mechanical energy can be produced in a variety of ways, often by combustion of a fuel, utilizing flowing water, or heating water into steam that will push against a turbine. The reverse process of going from electrical energy to mechanical energy in an electric motor utilizes a similar process. The application of a current to a coiled wire will produce a magnetic field that will oppose the field of a nearby permanent magnet, resulting in a torque on the coil producing rotational mechanical energy. This rotational energy can later be converted into nearly any other form of mechanical energy by some other intermediary deice.
What is formula for thermal efficiency?
Thermal Eff = (mechanical heat produced/electrical heat produced) x 100%
What form of energy is produced by Hydro?
Electrical energy produced from mechanical energy (kinetic energy) that moving turbines.
What is an explanation of how water makes electricity?
The hydroelectricity is produced by using the kinetic energy of falling water to drive turbines thus producing mechanical energy which is in turn converted to electrical energy.Dams are built across rivers for this.
Could Electrical energy be produced from mechanical energy?
Yes. All power stations do that.
