Greetings:
This is a technical question that concerns dc voltage so hopefully someone
that has knowledge in this area can help me with this.
I know that computers use low dc voltage of 12, 5 and 3.3 volts so hopefully
this will fit the mail list criteria.
I am a mechanic by trade. I am good at diagnosing electrical and
drivability. I have seen a few times that high resistance in the negative
leg of a circuit can take out components like computers, modules and even
not-so-complicated devices like bulbs and switches. What I don't understand
is why. Ohm's law states that E=IXR. If this is the case then if
resistance is high it will decrease amperage. I would tend to think that
just the opposite would happen...component would just lose power and not
fry.
Please enlighten me,
Jimbo
