Electricity may be static or dynamic (electric current)
Static electricity is scalar though it can be + or - signs, but nothing other than that.

Coming to current electricity, the dc current is scalar, as it has only one sign and does not get resolved.

Alternating current is vector. The current and voltages are not in the same direction always. Consider a capacitor for example, it may have a voltage of 100 V applied to it and might have current of 0.1 Amperes, but the power is still zero as the phase difference between current and voltage in case of capacitor is 90 degrees. In resistor it is 0 degrees. If you have series connection of capacitor and resistor, the angle between voltage and current will be between zero and 90 degrees.
The current can be resolved in direction of voltage and quadrature to it. Therefore, the alternating current is a vector.

The entirety of the work of Ampere, Faraday, Coulomb and others was formulated by Maxwell in his famous equations. most of the quantities are vector quantities, someone earlier said that voltage difference or potential is a vector quantity, it is not, voltage is a scalar. The amount of charge in Coulombs is also a scalar, the field produced by a charge and the force on another charge is a vector.

So the choice of the word electricity makes this question a bit vague.

If you are talking about current then this is a scalar and it is defined as the rate of change of charge with time.
Current density on the other hand is a vector and determines the current crossing through a plane in direction normal to the plane

It will depend on what electrical property is being measured.

The easiest way to distinguish between scalar and vector properties is to think of scalar as being the "amount" of something. e.g. like mass, or volume. Vectors have direction (e.g. velocity or force).

So if you measure the amount of electricity in Coulombs - that's scalar. It has no direction.

Voltage is the difference in electrical potential between two points - therefore it has direction.

electric current s a scalar, but current density s a vector.
current s either positive or negative, it cant have ne other direction, jus like integers which r either positive or negative. so if integers r scalars, so s electric current.
current density s current divided by area. area being a vector, makes current density a vector.

Electricity is of two types, static and an electric current, flowing. The lines of force are vectors. Flow of an electric current also sets up electric and magnetic fields which are vectors.

Electricity is a vector,because it has both magnitude and direction.As,electricity moves in a fixed direction(in its circuit)and also has magnitude(the capcity to do work-energy it possesse).Hence,i would say that electricity is a vector.

Dear, listen to me. electricity simply means current either AC or DC . current is a scalar quantity. because we add or substract current alzebrically . ( suppose at any junction current current of 2amp from north and 5 amp fron east meet then what is net current ? ofcourse it is 7amp(direction in addition of current has no significance .same result hold for electric charge. further query is welcomed .
thanks

electricity is a terminology
It is misinterpreted as the current
to some extent is the voltage or the power
Sometimes the bill

It is not either scalar or a vector

It is just a name
just like hydraulic , nuclear , physics

electricity is a vector in my opinion coz its easy to predict the direction it moves.. atleast in cases like huge machines like rotor
