| Oct 7, 2015 at 6:49 | comment | added | Sajid | It's the Same 12 V supply, would it cause problem when both are connected to 12V.? | |
| Oct 7, 2015 at 6:35 | comment | added | Ignacio Vazquez-Abrams | If you're going to try that then make sure you switch the one connected to the negative supply first... and make sure you understand the implication of having them both connected to the same supply. | |
| Oct 7, 2015 at 6:33 | comment | added | Sajid | Yes, but that is never going to happen. Lets say i want to reverse direction, I will Activate Relay 2 first then Deactivate Relay 1, So I don't see them being in air simultaenously. | |

| Oct 6, 2015 at 6:56 | comment | added | Ignacio Vazquez-Abrams | You forgot to account for the period when the armature is not touching either contact. That is when the EMF will be generated. | |
| Oct 6, 2015 at 6:53 | comment | added | Sajid | I have edited the question, please see it. | |
| Oct 6, 2015 at 6:50 | comment | added | Ignacio Vazquez-Abrams | Correct. But which path connects to the positive side? | |
| Oct 6, 2015 at 6:50 | comment | added | Sajid | I thought our aim is to provide path for the current to go from 1 lead of motor to another. | |
| Oct 6, 2015 at 6:47 | comment | added | Ignacio Vazquez-Abrams | You have a path from the motor to the lower potential to attempt to dissipate the negative EMF, but you lack any way to also get rid of the positive EMF other than to arc across the switches. As with any circuit, you need both connections in order for it to be effective. | |
| Oct 6, 2015 at 6:45 | comment | added | Sajid | Could you explain why is that needed? | |
