and output current are proportional to the number of turns of its\u00a0<\/span>
internal coil (both are the amount of alternating current).<\/span><\/p>\n
The voltage is rectified by the D10 switching diode and becomes a DC voltage V1.\u00a0<\/span>
V1 divides the voltage between R14 and R13.\u00a0<\/span>
The E6 electrolytic capacitor stabilizes the voltage V2 across the R13 resistor.\u00a0<\/span>
It is sent to the A\/D port of the chip for processing.<\/span><\/p>\n

the resistor R12 and the capacitor C8 filter out the high-frequency\u00a0<\/span>
components of the input and reduce its impact on the MCU.<\/span><\/p>\n
