Shocking Difference between Alternating Current and Direct Current

Current flows in two ways, either in direct current or alternating current. Arrows on the circuit shows the flow of electron in the conductor. The main difference lies in alternate and direct current is the direction of electrons flows are different. In DC the current flows are only one direction and in Ac the current go on switching between forward and backward direction periodically. By using AC we can transform the current to a larger distance. In any circuit the main components that include the circuit are sourced and load source can either be any electrical source or any other possible continuous source of electrical energy and the load can be any electrical load or anything else that must be driven by a continuous source of electricity. Electrons leaves the negative terminal of the source and enters the positive terminal of the source it continues till the circuit exists. It’s important to understand about the flow of current you can also gain some basic knowledge about this from your local electrician.

Alternating current

The amount of energy that can be carried by AC is high and it can be carried to a larger distance and can provide more power. The cause of direction of flow of current is due to rotating magnet along the wire. The frequency varies depending on the country for example 50 times per second in Europe or 60 times per second in the US. The main advantage AC current that provides is its easy to change the level of power through transformers and this mainly used by the power companies in order to save current and travel a long distance by using high voltage of current. Some electronic circuits operate only on direct current, some need frequent changes  that circuits use alternating current   and some circuits operate on both the alternating and direct current. It reverses its direction while flowing in a circuit from forward and backward directions. In AC it’s easier and cheaper to transform the voltage. We can insert plug in any of the direction in AC.

Properties of AC current include
·       Passive parameters are Impedance.
·       Power factor lies between 0 & 1.

Direct current
Direct current is the traditional way the flow of current but now the circuits are designed to use any of the direction either forward or backward. AC is 1.4 times less efficient than the alternating current because peak voltage is not the actual usable voltage, but the RMS or root-mean-square of the peak voltage is the actual voltage. It doesn’t travel to a large distance. The cause of DC is Steady magnetism along the wire. Frequency of direct current is zero. It’s flows only in one direction that is forward and it has a constant magnitude. DC obtains from a cell or battery.

Properties of DC current include
·       Passive parameter is a resistor.
·       Power factor always 1.
·       Types of DC are pure and pulsating.
