My relay coil 12v measure 100 ohm of resistance between pin 86 and 85 or between 85 and 86. A diode IN4001 is added in parallel to the coil.
However, after adding the diode, the coil has the same reading 100 ohm when measured between 86 and 85, and again vice versa, 85 and 86. Why? Is not the relay supposed to show resistance only in one direction????
Why the relay coil resistance still stays at 100 ohm after adding a diode in parallel with the coil??
