WebBut, it demonstrates the principle of how rectifiers work. It consists of only one diode inserted in an AC circuit. As a result, for each full cycle of the alternating current, the diode conducts only for half of the cycle but blocks the current for the other half. The outcome is shown in Figure 1c, which is a DC voltage as seen by a load. WebThis half-wave rectifier circuit can be built using one diode. This full-wave rectifier circuit can be built with two or four diodes. The transformer utilization factor for HWR is 0.287. The transformer utilization factor for FWR is 0.693. The basic ripple frequency of the HWR is ‘f’. WebExplain why the preceding flame proving systems called safety devices. ... In a flame rectification system, the pilot flame or main flame, can conduct electricity because it contains ionized combustion gases which are made up of positively and negatively charged particles.

"Flame rectification is a phenomenon in which a flame can act as an electrical rectifier. The effect is commonly described as being caused by the greater mobility of electrons relative to that of positive ions within the flame, and the asymmetric nature of the electrodes used to detect the phenomenon. This effect is used by rectification flame sensors to detect the presence of flame. The rectifying effect of the flame on an AC voltage allows the presence of flame to be distinguished from a res… " - Explain the principle of flame rectification
