I a bit new to electronics, about 1.
Now I'm learning about coils, and have a few questions.
I have some coils and I know their Henry rating, I've found a lot of information on coils. Now I'm wondering if I took a coil let's say a 55uH applied maybe 3v, what would be the voltage resulting. I've seen a coil used in a 3v to
9v dc-dc converter and that's why I'm wondering. I think the coil increases the 3v to some other voltage (the circuit used a 47uH), then an ic was used to regulate the output from the coil to 9v about. Is there a formula that could help me here.Or could I just build that simple circuit and using a multimeter safely read the voltage and amps that is being produced. What I'm worried that the voltage being produced is high and might damage my multimeter.
