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.
What else can I help you with?
Is current a scalar or vector quantity?
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.
What is the difference between vector and scalar quantities?
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 the measure of what?
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.
Is a force of friction a vector or scaler quantity?
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.
Voltage is a vector quantity or scaler quantity?
Scaler. Its vector counterpart is the electric field.
Is electric current scaler or vector quantity?
Electric current is a scalar quantity as it only has magnitude (typically measured in amperes) and no direction.
Is electric current or scalar quantity?
yes it is
Is electric current scalar quantity?
yes it is
Is current a scalar or vactor quantity?
Current is a scalar quantity, I= dq/dt.
Is resistivity vector or scalar?
Resistivity is a scalar quantity. It is a measure of how strongly a material opposes the flow of electric current through it.
Is electric potential a vector quantity?
No, electric potential is a scalar quantity, not a vector quantity.
Why electric charge is a scaler quantity?
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.
Is resistance a vector?
A vector quantity is one that has a magnitude (a number), and a direction. No, resistance is not a vector quantity; it is a scalar quantity (only magnitude).
Electrostatic potential is a Scalar Quantity or Vector Quantity?
Electrostatic potential is a scalar quantity. It represents the potential energy per unit charge at a given point in an electric field.
Electric potenial scalar or vector why?
Electric potential is a scalar quantity since work done and charge are scalars
Is current a vector or a scalar?
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.
Is a electric potential scalar or vector?
Electric potential is a scalar.
