Was so nice to catch up with you guys last night On online live lesson 👍🏻

When you can repair a module in house do you charge for the time taken or the amount a repair company would charge plus a little extra for convenience?? Or do you tell the customer you have sent for repair and do in house anyway😂

This was not my video but thought it was a great way to show if a relay does not have a diode or even a resistor the volts that is held in the coil when power is removed does have to go somewhere but with a diode it returns back to the coil and not to something external.
