Hello all. First time poster to the newsgroup.
I have a question about a ballast resistor. Would the ballast resistor
pictured here,
<http://moodle.student.cnwl.ac.uk/mo...al/ignition/conBreakComp/ballastresistor.html>
(an automotive ignition resistor) reduce voltage in an open circuit, a
closed circuit, or both? If it had 12v input and I connected a voltmeter
to the output side, with nothing else connected to it, would it read 12
volts or a reduced voltage.
Here is a statement I read:
Basic electrical thing: You always read full voltage on an open circuit.
Is this still true if there is a ballast resistor in the circuit? It
doesn't seem like it would be to me but I'm no electrical guru.
Thanks for any assistance you can offer…
Leon
