Hi Everybody,
I have a simple opamp circuit that has been running on a 9v battery very nicely, i want to change it to 12v as i have some rechargable 12v batteries now.
My question is that my batteries are 12v 1800mAhrs, is it possible my circuit could draw a lot more current from these batteries compared to the 9v batteries & fry something.
Or will the circuit only draw what is necessary & the same as before?
Do i need to regulate the voltage back to the original 9v or do i have to regulate the Amps Or just hook it up to the 12v battery.
One question turned into about a hundred--again.
Thanks
