How to replace SMD blue Led with conventional red LED?
"I heard that a blue LED has different voltage values than green and red ones. Green and red ones are easily replaceable, but how do I do that with the blue one?"
"I have to use the blue one, because green means fully charged and blue means charging."

Why doesn't any manufacturer create a multimeter that measures current in the same way as voltage?
"Current is measured by inserting a measuring device into the circuit to measure the flowing current. Voltage is typically measured in a circuit in parallel. Why isn't the current calculated from the voltage?"

I've made it that way.
It works fine.
Thank you all for your good advice. Thank you Richard for new video about caps...

"To complete this, differences from 14uF to 19.9uF are negligible, especially when there are 2 of them. This concerns a 230V refrigerator board that is 20 years old. Given that the refrigerator runs day and night, it's surprising that the capacitors have lasted 20 years."...

Can I replace 15uf capacitor with 22uf?
"If I wanted to replace an old 15uF/400V capacitor with a new one,
I have a new 15uF/400V and a new 22uF/400V capacitor. When measured, the new 15uF reads only 13uF, and the 22uF reads only 20uF. Can I use the 22uF capacitor?"
