How do I enter 10 to the power of -3 into the calculator?
Hello, Does anyone know how to enter 10 to the power of -3 (or other exponents) into a calculator? I know that for normal powers in standard notation, you press the EXP key, but for negative exponents?
Which power supply for 5V 1000mah battery?
Hi, I'm planning to upgrade my Dremel battery from 3.6V 700mAh to 5V 1000mAh because the original battery is defective. My question is, what power supply do I need to charge it? The original power supply is 6V, but I've learned that using 6V for a 5V battery can cause a defect, is that correct?
Circuit breaker trips in lamp circuit?
Hello everyone, I need help with a problem that has been occurring in my house for the past two days. The circuit breaker that protects three impulse circuits has been tripping. The strange thing is that it sometimes trips directly without a button being pressed, and sometimes it trips after the lights have been switched…
Minimum distances between tube sockets and PCB?
Hello everyone, Are there any empirical values or even regulations as to how large the minimum distance between the solder pads for tube sockets on circuit boards should or even must be? Voltage range up to 350V DC, maximum current 100 mA.
Is there a way to turn lights on or off with an Alexa routine?
ByTFrag
I'd like to create a routine that turns off the lights when a trigger is activated, and also do the same thing in reverse within a routine. Unfortunately, I haven't found anything that would work. Does anyone know how this could be solved? It's about Alexa routines and not other electronics.
Converting/repurposing rotary dial telephones?
Hello, I had the idea of digging out my old rotary dial phone from the basement and modifying it a bit. I'd like to know if I could theoretically use the dialing method to replace a button or an electronic signal on my Arduino? So, so to speak, I want to create the same effect…
Ua ist abhängig von der Größe und Polarität von Ud (=Differenz zwischen Up und Un) und von der Verstärkung des Operationsverstärker (OP).
Wird der Operationsverstärker übersteuert, dann ist Ua auch zusätzlich von der Betriebsspannung des OP abhängig von +Ub und -Ub.
Viel Erfolg!
