Question 472Electricity & Electronics - Assistant Engineer

The correct answer is C) half wave rectifier. A half wave rectifier is a type of electrical circuit that converts alternating current (AC) into direct current (DC) by allowing only one half of the AC waveform to pass through. This is the device shown in figure "A" of the illustration EL-0064. The other answer choices are incorrect because: A) a DC filter is a different circuit used to smooth out ripple in a DC signal, B) a full wave bridge rectifier is a more complex circuit that allows both halves of the AC waveform to pass through, and D) a full wave rectifier is also a more complex circuit that uses four diodes to achieve full wave rectification, unlike the single diode shown in the illustration.
