What is smallest source of electric current?
The electric current can be generated by different methods , The common sources are the generators ( Dynamos ) & the electrochemical cells ( electrolytic cells ) , The electricity which you use in your homes are produced from the large power stations where the dynamos exist where the wires .
Is electric cell a small source of electricity?
Answer: In a cell, chemical reaction takes place to produce electricity. Therefore, source of electricity in a cell is the chemical reaction taking place among the chemicals present inside it.
What are 5 sources of EMF?
The five sources of EMF are: Electromagnetism, Photoelectric, Thermoelectric, Piezoelectric and Chemical. Thermoelectric: A transfer of heat energy directly to electric energy.
Is an example of DC source?
Direct current is produced by sources such as batteries, thermocouples, solar cells, and commutator-type electric machines of the dynamo type. Direct current may flow in a conductor such as a wire, but can also flow through semiconductors, insulators, or even through a vacuum as in electron or ion beams.
What are two sources of current?
A cell and battery are the two sources of current.
What are types of current?
There are two kinds of current electricity: direct current (DC) and alternating current (AC). With direct current, electrons move in one direction. Batteries produce direct current. In alternating current, electrons flow in both directions.
What is current and electricity?
Electric current is the movement of electrons through a wire. Electric current is measured in amperes (amps) and refers to the number of charges that move through the wire per second. … If we want current to flow directly from one point to another, we should use a wire that has as little resistance as possible.
