Hi Every body
I Had a circuit where three components, connected in series (2000-ohm resistor then Indication lamp & then relay coil) across the 125V DC source. These components are rated for 120 V DC. Under this situation the relay coil didn’t get energized because of not sufficient voltage to pick-up the relay coil.
Recently I replaced existing relay with different type of relay having same voltage rating. Now I had the problem, as this relay is getting energized when the circuit is powered-up.
Other data I have is original relay coil wattage was 4.5 W & new coil wattage is 7.8 W.
I want to know why the new relay is picking-up.
