sabog din yan as i said before naka step down na yung output ng capacitor para sa supply ng energy IC mo basta wag mong iibahin ang circuit ng power analyzer please???

bale istep down ng cap ang 220ac noh?

pero meron rectifier after sa cap, maconvert p rin nia sa DC dba? (matigas ang ulo nito heheheheh)

halfwave rectifier 220Vac peak mangyayari try mo lang para charge to experience bili kana lang ulit pag nasira at least naprove mo

ung figure 3 na transformerless resistive ac to dc supply. ok kaya yan xa?

ito ung schematic diagram ng power analyzer ng e-gizmo.

yang nakaenclose ng circle in red is ang BLUE CAPACITOR and RESISTOR in series para sa power supple ng
power analyzer.

gitry ko palitan ng resistor only ung series combination ng cap and resistor. nagwork ang poweranalyzer.

pero ask lng ako, ano ang disadvantage and consequences ng resistive lng na power supply ?
parang sinunod ko na ung Figure 3 (resistive) dito sa link na ito

^
May improvement ba sa expected measured value when you changed the capacitor to a resistor. I my self had doubts before about the measured AC voltage and I used 4 digital multimeter to compare the voltage readings.

All I observed was that all 4 DMM was giving random results within 10V of the power analyzer reading.
