What is the relationship between electricity and magnetisum?
The magnetic field will be perpendicular to the electric field and vice versa.More DetailAn electric field is the area which surrounds an electric charge within which it is capable of exerting a perceptible force on another electric charge. A magnetic field is the area of force surrounding a magnetic pole, or a current flowing through a conductor, in which there is a magnetic flux. A magnetic field can be produced when an electric current is passed through an electric circuit wound in a helix or solenoid.The relationship that exists between an electric field and a magnetic field is one of electromagnetic interaction as a consequence of associating elementary particles.The electrostatic force between charged particles is an example of this relationship.
Electricity will flow only if an electrical circuit is?
if an electric circuit has potential difference. Electricity will flow only if an electrical circuit is closed.
What is a current in a circuit measured in?
ampsAnswerElectric current is measured by means of an ammeter. Electric current is expressed in amperes (symbol: A), which is defined in terms of the magnetic effect of an electric current -i.e. the force between two, parallel, current-carrying conductors.
What is open circuit and short circuit?
Consider two points (A and B) in an electric circuit. An open circuit between A and B means there is no electrical connection between A and B. A short circuit between A and B means there is an electrical connection between A and B.
What are normally open and close circuits?
The electric path which starts from the positive terminal of a cell or battery ends at its negative terminal, without any break, is called closed electric circuit or complete electric circuit. The electric path,which starts from the positive terminal of a cell or battery, is broken at some point, is called open electric circuit or incomplete electric circuit.
What is the difference between electric and electrical?
Pronunciation. An electrical circuit is the exact same as the electric system.
What 3 terms are used to describe electric pressure?
Voltage: This measures the electric potential energy between two points in a circuit. Electromotive force (EMF): It represents the push that drives the electric current in a circuit. Potential difference: This is the difference in electric potential between two points in a circuit, causing the flow of current.
Application of electrical circuit analogies in magnetic circuit?
Magnetic circuit follows equation (4) that is Ni = (Ф) ( l / μA) or m.m.f(magneto motive force) = (Flux) (reluctance).Electric circuit follows ohm's law that is E = I.R or e.m.f(electro motive force) = (current) (Resistance)From above point m.m.f in magnetic circuit is like as e.m.f in electrical circuit.Flux in magnetic circuit is similar as current in electrical circuit.Reluctance in magnetic circuit, S = ( l / μA) is similar to resistance R = (ρl/A) in electric circuit.Permeance (= 1/reluctance) in magnetic circuit is equivalent to conductance (=1/resistance) in electric circuit.In magnetic circuit flux establishes but not flow like as current in magnetic circuit.In magnetic circuit energy needed only to establish the flux but no consistent energy need to maintain it whereas in electric circuit continuous energy needed to flow of current.Resistance of an electric circuit is constant (for same temperature) and is independent of current but reluctance of magnetic circuit is not constant because it depends on μ (=B/H) which is not constant and depends on B/H.
What do you use a volmeter for?
A voltmeter is used to measure the voltage difference between two points in an electrical circuit. It helps in determining the electric potential or the electric pressure in a circuit.
What flows through a circuit and causes a magnetic field?
An electric current flowing through a circuit causes a magnetic field. This is due to the movement of electric charges, usually electrons, in the circuit. The magnetic field produced is perpendicular to the direction of the current flow.
What is the difference between a series circuit and as parallel circuit?
series circuit can only move on one patha parallel circuit has two more paths for the electric carve to follow
What causes current to flow in a circuit?
Current flows in a circuit when there is a difference in electrical potential (voltage) between two points, creating an electric field that pushes the charged particles (usually electrons) through the circuit. This movement of charged particles is what we know as an electric current.
Compare magnetic circuit and electric corcuit?
A magnetic circuit describes the flow of magnetic flux through a material, typically consisting of a magnetic core and windings. An electric circuit, on the other hand, describes the flow of electric current through a path that includes components like resistors, capacitors, and inductors. Both circuits involve the transfer of energy, but magnetic circuits focus on the flow of magnetic fields, while electric circuits focus on the flow of electric charge.
What describes resistance to movement to magnetic lines of force?
Resistance to movement of magnetic lines of force is described as reluctance. Reluctance is similar to resistance in an electric circuit and is a measure of the opposition that a magnetic circuit offers to the magnetic flux. It depends on the material and the geometry of the magnetic circuit.
What is magnetic relunctance?
Reluctance is the opposition offered by a magnetic circuit to the formation of magnetic flux. It is equivalent to resistance in an electric circuit.Reluctance is the ratio of a magnetic circuit's magnetomotive force (measured in amperes) to its magnetic flux(measured in webers, pronounced 'vay-bers'). So, reluctance is measured in amperes per weber (which is often 'spoken' as 'ampere-turns per weber'). This is equivalent, in an electric circuit, to the ratio: electomotive force to electric current.
What is the potential difference between two points in a circuit is called?
Voltage drop
What will happen if you place a magnetic compass in an electric curcuit?
Placing a magnetic compass in an electric circuit would interfere with its ability to accurately point to the Earth's magnetic north. The magnetic field generated by the electric current in the circuit would cause the compass needle to deflect from its normal orientation.
