What describes an electric generator?
An electric generator is a device that converts mechanical energy obtained from an external source into electrical energy as the output. … Instead, it uses the mechanical energy supplied to it to force the movement of electric charges present in the wire of its windings through an external electric circuit.
Which best describes what happens in an electric generator?
Which best describes what happens in an electric generator? … Motion causes constantly changing magnetic fields to induce electrical energy.
Which of the following statement describes how a generator functions?
Which of the following statements describes how a generator functions? A generator uses physical work to rotate magnets thereby inducing an electrical current. … A motor works by electrical energy moving a charge through a loop in a magnetic field, causing the loop to rotate.
What is electric generator class 10th?
Hint: An electric generator is an electronic device which converts the mechanical energy into electrical energy. The electric generators are operated on electrostatic principles, based on the phenomenon of the electromagnetic induction.
How does a generator generate electricity?
How Do Generators Create Electricity? Generators don’t actually create electricity. Instead, they convert mechanical or chemical energy into electrical energy. They do this by capturing the power of motion and turning it into electrical energy by forcing electrons from the external source through an electrical circuit.
What does a generator do?
An Electric generator is a device which is used to produce electric energy, which can be stored in batteries or can be directly supplied to the homes, shops, offices, etc. Electric generators work on the principle of electromagnetic induction.
How does an electric generator work quizlet?
How does an electric generator work? The axle rotates the armature in the magnetic field of a permanent magnet, which induces an electric current. The armature rotates the axle in the magnetic field of a permanent magnet, which induces an electric current.
Which best describes what should happen to the needle that measures electric current?
As Keisha runs the generator, which best describes what should happen to the needle that measures electric current? It will move back and forth between a large positive and a large negative value.
On which principle does a generator work?
Modern generators work on the principle of electromagnetic induction, a term coined by Michael Faraday when he discovered that a conductor moving in a magnetic field can create and direct electrical charges.
Which of the following describes the potential difference?
Potential difference is the difference in the amount of energy that charge carriers have between two points in a circuit. **Measured in Volts: **Potential difference (p.d.) is measured in volts (V) and is also called voltage.
What is a device that transforms electrical energy into mechanical energy?
An electric motor is a device that uses an electric current to turn an axle. An electric motor transforms electrical energy into mechanical energy.
