rectifier. not unique to laptops.
A laptop runs on DC. Either from the battery, or the external power supply, which converts AC power to DC.
A "Rectifier" converts AC current to pulsating DC current.
A Rectifier converts Alternating current into Direct current
capacitor is component used to store and release the electric charge.and also it has feature to block the dc but bypass ac.and inverter is device which converts ac to dc and then again ac
Diode rectifier
While 'rectifier' is the component which converts AC to DC, the entire converter unit which converts AC to DC is also known by the name 'Eliminator'.This, as the old timers will tell you, is short for 'Battery Eliminator', as quite often, the AC-DC converter is used as a substitute for having to use the batteries. It allows the battery driven equipment to be powered from the mains directly.
its commutator..which converts ac produced by and motor to pulsating dc ... more the commutator divide more accurate dc..means less pulse in dc
By using rectification we can convert the AC into DC....
As in all electronics devices that obtain power from the AC electric system, a power supply converts the AC to the DC voltage(s) needed by the electronics in the device. Depending on the needs of the device this power supply may deliver a single DC voltage or as many as several dozen different DC voltages.
Diode: Which allows power in one direction or which converts AC to dc . Converter: Which converts DC to DC
A: It is a regular DC voltmeter but the AC is rectified and the DC component is measured and displayed as AC VOLTS.
the answer is Rectifier. it converts ac voltage into dc which can apply to the dc device
