Name 4 different types of energy which can be converted into electrical energy to produce an emf?
i dont even know there four words
Can TV and Radio towers produce EMF?
Well, it's not actually the tower that produces the EMF. It's the RF energy radiated by the antennas that are mounted on the tower. That energy produces EMF in receiving antennas, which alternates (wiggles) at the frequency of the transmitted signal. All of this is very lucky. Without that little EMF induced in the receiving antenna, there would be no such thing as radio communication.
What three things are required to produce EMF in an alternator?
armature, stator, rotor
Is free energy of cell reaction positive when emf of cell reaction is positive?
G = -nFE Therefore, G will be negative when EMF is positive.
Describe how you convert various types of energy into electrical energy?
Electrical energy could be produced from so many energy. Solar energy. This would help some voltaic cells to produce some potential difference which in turn would drive current when it is connected to an external device. Chemical energy. As we use cells, there chemical energy with its tendency such oxidising etc would create an emf between the terminals of the cell. Hence current flows as we connect the terminals to a device. Magnetic energy. Using magnetic energy and mechanical energy emf is produced as the magnetic flux linked with the coil changes. This is known as phenomenon of electromagnetic induction. Once again using thermal energy, by maintaining the junctions of thermocouples at two different temperatures, thermo emf will be produced.
What is voltage sources?
It is the souce that produce the emf force that drive the electron in a metal material
How do you generate electricity from a turbine?
A wire moving in a magnetic field will automatically produce an emf (a voltage).
How is lenz's law special case of the law of conservation of energy?
Lenz's law is a special case of the law of conservation of energy because it describes the relationship between the induced electromotive force (emf) and the change in magnetic flux in a closed loop. According to Lenz's law, the direction of the induced emf will be such that it opposes the change in magnetic flux, leading to the conservation of energy. This means that any change in the magnetic field will result in the generation of a current or emf that counteracts that change, thereby conserving energy.
What emf stands for?
Electromagnetic field (induces around the metal when current flows through it). Another opinion: Nope ! 'EMF' stands for 'Electromotive Force' . We refer to it casually as 'voltage'.
Does a magnetic field produce electricity?
ANSWER yes. When it moves it induces EMF in metals, laser beams, gravity field and other magnetic fields. Move as in expand and contract or as in moving the EMF generator.
Why magnet is used for making standard resistance coil?
magnet produce emf it maintain the resistance as same
How energy is transferred from stator to rotor?
when current is passing through the stator windings of motor magnetic field is develop ,due to it emf is produced inside the stator windings,that emf is further cuts the emf across stator due to which current flowing inside the rotor.
