Difference Between Alternating Current & Direct Current
The difference between alternating current and direct current is given below.
AC (Alternating Current) |
DC (Direct Current) |
---|---|
AC is characterized by the continuous and periodic change in the direction of electric charge flow. |
DC flows in one direction, from a positive terminal to a negative terminal. |
The electric charge in an alternating current circuit switches direction, often in a sinusoidal (wave-like) fashion. |
It maintains a constant voltage level over time, which can be achieved using batteries or rectifiers that convert AC to DC. |
Because it can be easily changed to different voltage levels using transformers, alternating current (AC) is the type of electricity provided to homes and businesses, making long-distance transmission more efficient. |
Because many electronic components require a constant voltage source, direct current (DC) is extensively utilized in electronic devices such as laptops, smartphones, and most portable gadgets. |
Types of Current
The movement of charged particles within a conducting medium is generally referred to as current. The term “charged particles” in relation to electricity primarily refers to electrons. The conducting material’s atoms have free electrons that can travel from one atom to another. The electrons move in a random manner. Alternating and direct current are the two main forms of current.
In alternating current, the current’s direction is reversed, whereas in direct current, electrons flow in one direction. In batteries, you can find direct current. In a battery, the electron always moves from the negative side to the positive side. Alternating current, on the other hand, can be used in televisions, kitchen appliances, etc.
