Hi,
Look at the 2 diagrams below - My basic query is "which one is correct?"
I think that Circuit #2 is correct becuase the circuit #1 will cause osculation of the back-EMF when the relay is turned off becase the current cannot escape to GND (directly) and hence will have to be disapated in the relay coil.
Whereas in Circuit #2, when the relay turns off, the back-EMF is shorted directly to GND.
Can anyone confirm for me please?
