Is AC current a vector?

It has long been known that in any simple alternating-current circuit, the current and voltage may be conveniently regarded as rotatable vector quantities. It is also known that the power in such circuits is not to be regarded as the vector product of the rotating vector voltage and rotating vector current.

What is the relationship between current and voltage in AC circuit?

Capacitors in AC circuits If the AC supply is connected to a resistor, then the current and voltage will be proportional to each other. This means that the current and voltage will “peak” at the same time. We say that the current and voltage are in phase.

Can voltage be a vector?

No, the voltage is not a vector. The voltage is the difference in the electric potential, wich is a scalar.

Why is there phase difference between voltage and current in an AC circuit?

When capacitors or inductors are involved in an AC circuit, the current and voltage do not peak at the same time. It is customary to use the angle by which the voltage leads the current. This leads to a positive phase for inductive circuits since current lags the voltage in an inductive circuit.

Is AC voltage a scalar or vector?

Though voltage and current in ac circuit are represented by phasors – rotating vectors, they are not vectors themselves. They are scalar quantities.

Why current is a vector?

Note: Current is a vector because it has a magnitude and a direction. Since current doesn’t obey it and it follows algebraic addition, currents are scalar.

What is the relation between current and voltage in an AC circuit containing only capacitance?

Voltage lags current by 90° in a pure capacitive circuit. In a pure capacitive circuit, the instantaneous power may be positive or negative. As with the simple inductor circuit, the 90-degree phase shift between voltage and current results in a power wave that alternates equally between positive and negative.

What is the phase relation between current and voltage in an AC circuit containing an ideal capacitor?

Show that the current leads the voltage in phase by pi/2 in an AC circuit containing an ideal capacitor.

Is electric current a vector?

Is voltage a vector or scalar?

scalar quantity
Voltage is a scalar quantity and can be calculated by the product of current (scalar) and resistance (scalar). Work is a vector quantity and can be calculated by the product of a force (vector) and displacement (vector).

What is the difference between voltage and current in AC circuit?

The phase difference between current and voltage in an AC circuit is 4Π​ radian.

What is the phase difference between voltage and current in an AC circuit containing a capacitance?

Phase difference between voltage and current in a capacitor in an ac circuit is. In a capacitive ac circuits, the voltage lags behind the current in phase by π/2 radian.
