Transformerless power supplies are ... a few tens of milliamps, that resistor is going to get hot fast. A better component to use in the top of the divider is a capacitor, with its reactance ...
He’d already had the life-expired electrolytic capacitors replaced on the mainboard, so the chief suspect was the power supply ... them through a suitable resistor until you can no longer ...
Most modern electronic devices consist of several key components: transistors, capacitors, resistors ... Active components rely on an external power source to control or modify electrical signals.
