Hi all,
I'm designing a very simple doorbell circuit. I am very new to
electronics, so I'd really like to verify my idea with someone.
I'll get a 10mA, 12 volt piezo buzzer from Radio Shack and plan on
running a 12 volt battery in series with a 1200 ohm resistor to the
buzzer from a push button.
I'm using 1200 ohm resistor based on R = V / I, that is 12
volts / .01 amps = 1200 ohms.
I have a paranoia about starting a fire -- under what conditions,
if any, could a circuit like this start a fire?
Thanks so much if anyone wants to indulge in such an elementary
post....
