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.
Is a current a vector or scalar?
scalar. although current has magnitude(1A,20A,5A etc) and direction but it does not follow vbector laws. hence it is a scalar quantity
What is a scalar times a vector?
A scalar times a vector is a vector.
Is inertia is a scalar or vector?
vector
Is AC a vector or scalar quantity?
AC is a vector quantity because it has both magnitude and direction. Velocity, force, and displacement are examples of vector quantities, and they can be represented by arrows in the appropriate direction.
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 electric current scaler or vector quantity?
Electric current is a scalar quantity as it only has magnitude (typically measured in amperes) and no direction.
Can you add a scalar to a vector?
Yes, you can add a scalar to a vector by adding the scalar value to each component of the vector.
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.
Multiplying or dividing vectors by scalars results in what?
When multiplying a vector by a scalar, each component of the vector is multiplied by the scalar. This operation changes the magnitude of the vector but not its direction. Similarly, dividing a vector by a scalar involves dividing each component of the vector by the scalar.
Can a scalar quantity be made into a vector quantity by adding a direction to its magnitude why or why not?
Yes this happens in case of area. Usually area is a scalar quantity. But we provide the direction of course perpendicular to its plane area we make it as a vector. Same way though electric current is not a vector it is sensed as vector as we put along with length of conductor. I is scalar but Idl is vector.
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).
