For a physical quantity to be termed a vector quantity, having magnitude and direction is not enough. The quantity should obey the laws of vector addition too. Like the triangle law or the parallelogram law. As we know, if two currents meet at a junction, the total current of the resultant current will be the algebraic sum of the two current and not the vector sum.
Sometimes, treating a current like a vector makes sense, like when the current though a conductor induces a magnetic field.
Electric current is defined as the rate of flow of charge
So I = q / t
Here both q, the electric charge and t, time are scalars. Hence their ratio ie current is a scalar.
because in that we don't have to depict the direction only magnitude
Electric current is the time rate of change of the scalar charge, thus it is a scalar quantity. The scalar derivative of a scalar value is a scalar value.
It depends upon the condition.But basically, to be a vector, the physical quantities needs to follow vector algebra.but current dos not follow it so it is scalar quantity.
Vector quantity is a quantity characterized by magnitude and direction.Whereas,Scalar quantity is a quantity that does not depend on direction.
An electric current is a movement of charges, and it is measured in amperes or just amps. An ammeter is used to make this measurement. Current flow is a scalar quantity, and it refers to the number of charges passing a given point per unit of time.
Either, or both. Motion can be described in either vector or scalar terms. Speed is a scalar quantity, having only a magnitude. Velocity is a vector quantity, having both magnitude and direction. Acceleration is a vector quantity.
Scaler. Its vector counterpart is the electric field.
Electric current is a scalar.
yes it is
yes it is
Current is a scalar quantity, I= dq/dt.
Current is a scalar if it is given as a scalar - such as 5A. There is no direction connected with this. If it is referenced to a voltage - 5A at 30 degrees lagging the voltage - then it is a vector quantity.
Definitely current is a SCALAR. Current density, of course, is a vector quantity Current = charge / time Both charge and time are scalars Current density = current / area Here area is a vector quantity Hence scalar product of current density and area give scalar quantity i.e. current. So electric current is a scalar Of course we assign +ve and -ve sign to currents. It is not because of direction as we do incase of vectors. But it is only algebraic sign.
current is vector or scalar
Electric potential is a scalar quantity since work done and charge are scalars
It depends upon the condition.But basically, to be a vector, the physical quantities needs to follow vector algebra.but current dos not follow it so it is scalar quantity.
Those having only magnitude but no direction are known as scalar quantity. Time, mass, work, power, electric current, electric charge, moment of inertia, magnetic flux, electric flux and so many are found to be scalar in this world.
scalar. although current has magnitude(1A,20A,5A etc) and direction but it does not follow vbector laws. hence it is a scalar quantity
no, it's a vector dude
