What parts of an electric generator are connected?
The parts of an electric generator that are connected are the armature and commutator. An armature generally refers to one of the two principal electrical components of an electromechanical or electrical machine.
How does electricity flow in an electric circuit?
The direction of an electric current is by convention the direction in which a positive charge would move. Thus, the current in the external circuit is directed away from the positive terminal and toward the negative terminal of the battery. Electrons would actually move through the wires in the opposite direction.
Why is air a bad conductor of electricity?
In gases, electric conduction occurs by the movements of both positive and negative charge-carriers, ions. Air is a mixture of neutral or inert gases. Therefore it contains few or no charged particles or free ions for conduction of electricity. Hence, air is a poor conductor of electricity.
Which of the two is better conductor of electricity?
Answer : Sea water is a better conductor because it contains sodium and chloride ions in large amounts. These ions make the solution conducting and thus, sea water is considered better conductor than the tap water which does not contain ions in large amounts.
Which out of distilled water tap water and sea water is the best conductor of electricity?
Tap water is a conductor of electricity because it has some ions namely sodium and potassium ions. Seawater is a good conductor of electricity because it is a rich source of sodium ions. Therefore, sea water is the best conductor of electricity.
Which of the two is better conductor of electricity drinking water tap water or sea water give reason?
Which of the two is a better conductor of electricity: drinking water (tap water) or seawater? Give the reason for your answer. Solution: Seawater is a good conductor of electricity because it has sodium and chloride ions which are responsible for the electric charge and electrical conduction.
Which of the following is not a conductor of electricity?
NaCl which is also known as common salt is solid in state and solid ions or compounds don’t conduct electricity.
Which metal is not a good conductor?
Tungsten and Bismuth are metals which are poor conductors of electricity. There are many, but some include Aluminum, Bismuth, Gallium, Indium, Lead, Thallium, Tin, Ununhexium, Ununpentium, Ununquadium, and Ununtrium.
Is petrol a conductor of electricity?
question_answer Answers(1) The typical value of the electrical conductivity of petrol is 25 pSm-1 . This is very low for petrol to conduct. So petrol is a poor conductor of electricity.
