Hint: Direct current (DC) is the transfer of electric charge in just one direction. It is the steady state of a fixed-voltage circuit. Most well-known uses, however, use a time-changing voltage source. An alternating current (AC) is the movement of an electric charge that is regularly in the opposite direction. If the source changes periodically, especially sinusoidally, the circuit is identified as an alternating current circuit.
Complete step-by-step solution:
Electric current moves in two ways: alternating current (AC) or direct current (DC). In alternating current, current keeps changing directions periodically – forth and backward. While in the DC, it runs in a single direction regularly. The main variation between AC and DC occupies the direction in which the electrons move. In DC, the electrons run steadily in one direction while electrons persist, switching directions, going forth, and then backward in AC.
The primary use of DC is to provide power for electrical appliances and also to charge batteries. Example: flashlights, mobile phone batteries, flat-screen television, and electronic vehicles.
Everything that operates on a battery and utilizes an AC adapter while using a USB wire for energy relies on DC.
Note: Most high-power distribution arrangements are AC. Moreover, the power is transferred at much greater voltages than the $120-V\ AC$. Economies of range make it affordable to make a few concrete electric power-generation plants than to create many small ones. This requires sending large power distances, and energy wastes in the path must be decreased. High voltages can be transferred with much fewer power losses than moderate voltages.
