Which rectifier requires four diodes? 0 half-wave voltage rectifier none of those techniques full-wave voltage rectifier via a transformer RC based rectification full-wave bridge voltage rectifier Question 2 Regarding diodes, we cannot state that Not yet answered Onone of these statements Marked out of 2.00 They allow electrical current to flow on only direction, blocking currents coming from the opposite direction. They can only work as conductors Every diode has polarity Flag question The positive pole is called anode and the negative pole is called cathode
