What kinds of current are produced by a battery and by a generator?
Direct current is produced by batteries, fuel cells, rectifiers, and generators with commutators. Direct current was supplanted by alternating current (AC) for common commercial power in the late 1880s because it was then uneconomical to transform it to the high voltages needed for long-distance transmission.
Does a generator produce electric current?
It is important to understand that a generator does not actually ‘create’ electrical energy. This movement creates a voltage difference between the two ends of the wire or electrical conductor, which in turn causes the electric charges to flow, thus generating electric current.
What are 5 sources of EMF?
The five sources of EMF are: Electromagnetism, Photoelectric, Thermoelectric, Piezoelectric and Chemical.
What is electric generator principle?
Electric generators work on the principle of electromagnetic induction. A conductor coil (a copper coil tightly wound onto a metal core) is rotated rapidly between the poles of a horseshoe type magnet. The magnetic field will interfere with the electrons in the conductor to induce a flow of electric current inside it.
How is an alternating current produced in an electric generator?
An alternating current is produced by an electric generator. An electric generator consists of a magnet and a loop of wire which rotates in the magnetic field of the magnet. As the wire rotates in the magnetic field, the changing strength of the magnetic field through the wire produces a force which drives the electric charges around the wire.
How to calculate the current of a generator?
If the generator above were connected to a circuit of resistance R = ohms, the electric current would be I = V/R = amperes for velocity perpendicular to B. The power supplied to the circuit would be P= VI = watts.
What kind of energy does an AC generator produce?
In the next section, let us learn more about AC Generators. AC generator, also known as alternators, is a machine that converts mechanical energy into electrical energy. The generated electrical energy is in the form of an alternating current sinusoidal output waveform.
Where does current and power from a generated voltage come from?
Current and Power From a Generated Voltage. When a conductor moves through a magnetic field, there will be a generated motional emf. This is one example of Faraday’s Law and it arises from the magnetic force. The voltage generated in a length of wire, presuming that the entire length moves through a uniform field, is given below.
