Why is electric current a scalar quantity?
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 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.
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.
Name scalar fields and vector fields?
name as many scalar fields and vector fields as u can?
Voltage is a vector quantity or scaler quantity?
Scaler. Its vector counterpart is the electric field.
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).
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.
A vector quantity has direction a scalar quantity does not true or false?
True. A vector quantity has both magnitude and direction, while a scalar quantity only has magnitude.
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 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 temperature a scalar quantity or vector quantity?
temperature is a scalar quantity................
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 length a scalar quantity or a vector quantity?
length is a scalar quantity buddy . but displacement is vector quantity. Length is a vector quantity If it is associated with direction.. Because having direction make it vector... S0 being vector or scalar depends upon how and where it is used..
Why cant a vector quantity be added to a scalar quantity?
vector quantity is magnitute and direction scalar is magnitute only
Is the following measurement a vector quantity or a scalar quantity?
A vector quantity.
Is scalar quantiy is added with vector quantity?
A scalar quantity added to a vector quantity is a complex quantity. An example is a complex number z = a + ib, a is the scalar and ib is the vector quantity.If the vector quantity is 3 dimensional, ib + jc + kd, then the scalar and vector forms a quaternion quantity.
Is the work vector quantity or scalar quantity?
Work is a scalar quantity.
