Therefore, the Direct Current is always denoted by Positive (+) & Negative (-) Marking Generationĭirect current can be generated in many ways. Since the direction of the current does not change the polarity of its voltage also do not change. It is unidirectional current that flows in only one direction and unlike AC’ it does not flow backward. The type of electric current whose direction does not change is called Direct Current or DC.

In order to deliver full power to the load, the AC voltage and current needs to be synchronized (or in-phase). In such cases, the magnitude of one wave lags behind the magnitude of the other wave. The phase difference is the difference with respect to the time shift between the two AC waves. Because the definition of power factor is cos (θ) where θ is the phase difference between the voltage waveform and current waveform We can also say that this is the reason the power factor is involved in only AC systems. The reactance causes a phase difference between the voltage & current waves. Therefore, the alternating current introduces reactance to the circuit.
We already know that alternating current has a specific frequency and we know that frequency affects the reactance of the capacitor and inductor. the most common waveform of AC that we use in our homes is sine wave. The resultant waveform could be a sine wave, square wave, triangular wave, saw tooth, etc. It oscillates between its maximum peak point and its minimum peak point along a common reference point. The magnitude of the alternating current and voltage varies continuously through time. Since the rotating coil reverses the polarity of the magnetic field, the electric current and voltage induced in the coil changes its direction periodically. The rotation of the coil varies the magnetic field lines affecting the coil therefore an electric current is induced in the coil. The alternator is made up of a coil that rotates (by any means such as water or steam turbine) inside a stationary magnetic field. This principle is applied in the devices called Alternators which is used for the generation of Alternating current. When a coil or a loop of wire is placed in a varying magnetic field, it induces an electric current in the coil. The number of times electric current changes its direction in one second is called its frequency and it is commonly 50 Hz (Europe) or 60 Hz (US). Therefore, Alternating current is denoted by a wave (~) sign. the high potential (+) and low potential (-) swaps together. Since the direction of the current reverses periodically, the voltage polarity also reverses i.e. When the direction of the electric current reverses periodically, it is said to be Alternating Current.
