Hint :The term "alternating current" refers to the fact that the current is continually changing direction. Mains power is an alternating current (AC) supply, with a voltage of around 230 volts in the United Kingdom. It has a frequency of 50 hertz (hundredths of a second), which means it changes direction 50 times each second. It's more efficient at carrying current over long distances, which is why we use it for power lines.
Complete Step By Step Answer:
Because alternating current is accessible from power stations, the TV's primary supply is built to work with it. The majority of the components in a television run on direct current. Rectifier circuits in televisions transform alternating electricity into direct current.
A rectifier is an electrical device that transforms alternating current (AC), which flips direction on a regular basis, to direct current (DC), which only travels in one direction. The inverter performs the reversing action.
The procedure is called rectification because it "straightens" the present course. Vacuum tube diodes, wet chemical cells, stacks of copper oxide plates, semiconductor diodes, silicon-controlled rectifiers, and other silicon-based semiconductor switches are all examples of rectifiers. Rectifiers have a wide range of applications, although they're most commonly used in DC power supply and high-voltage direct current power transmission systems.
The output voltage may require extra smoothing to achieve a uniform constant voltage, depending on the kind of alternating current supply and the layout of the rectifier circuit. Many rectifier applications, including power supply for radio, television, and computer equipment, need a constant DC voltage (as would be produced by a battery). In some applications, the rectifier's output is smoothed by an electronic filter, which might be a capacitor, choke, or a combination of capacitors, chokes, and resistors, followed by a voltage regulator to create a constant voltage.
Note :
Direct current (DC) is a one-way electric charge flow. A good example of DC power is an electrochemical cell. Direct current can flow via a wire, but it can also flow through semiconductors, insulators, or even a vacuum, as in electron or ion beams. Electric current is distinguished from alternating current by the fact that it travels in a continuous direction (AC).
