Great video. I’ve been using solenoids relays and valves for a while but I never understood the science behind them ..5 minutes later and now I’m a pro 🤙

Hi, one solenoid in a home that you forgot to mention is the common doorbell chime, which normally gets its power from a transformer (usually located attached to the breaker box) that converts 120 V AC to the 16 V AC needed to run the mechanical doorbell solenoids. When the doorbell (a simple switch) is pressed, the circuit is closed, and current is sent through the coil, retracting the metal plunger and causing it to strike the "DING" chime plate. When the doorbell is released by the person's finger, the circuit opens again, and a spring snaps the plunger back, where it hits the opposite "DONG" chime plate. (The rear doorbell, which has its own solenoid, simply blocks the second strike with a rubber stopper, so you get only the "DING" chime.) You have demonstrated that DC voltage CAN, in fact, be used to run a solenoid circuit. (I had read that this was true, but had been told by various doorbell sales people that -- NO NO, it must be AC.) When I connected up a 9-volt battery, however, the plunger moved a wimpy fraction of an inch, and did not strike the chime plate. Why does your 6 V DC circuit work, but my 9 volt DC circuit didn't? (Assuming the common nail and the metal plunger are somewhat similar.) Does it have to do with a difference in current supplied by your 4 AA's in series versus one 9 volt? And how could I, just for proof of concept, actually run my doorbell off of some batteries? (I just hate it when someone tells me something "can't be done.")

Basically I was taught in summary a relay is a switch, controlled by a low amperage signal wire to control a large amperage circuit. What is the purpose? In my opinion to reduce the amount of costs and inefficiency or wiring. If relays didn't exists you would have to run a wire the size of a battery cable to start your car too the ignition switch. High amperage = big wire, low amperage = small wire.

You said that the coil in a solenoid gets hot. How do car relays stay on and not cook and melt?

@Rossvallance 8 жыл бұрын

They don't stay on running current longer than designed. Most will have a switch lock, eg the door lock, relati switches between lock or unlock. Or as for your indicators, the flash relay will rarely run longer than designed, and even then the current passing is minimal. The gentleman who uploaded ran what looks like 4 X AA batteries at 6v total and a fair current ( maybe two amp) which is 12 watts through a thin wire, the resistance isn't high in copper but it still gets h o tt hot with the flow of current needed to lift the approximate 15 g nail with ample force again earth gravity :). ... Science bi*** , jokes.

@ellamayveloso5799 8 жыл бұрын

solenoids do get hot if power stays on like an RC actuator

@Rossvallance 8 жыл бұрын

but they are designed to only pass current whilst they are on, which is the time taken to activate the switch.

+Engineer mapmaker909 that's not correct. A solenoid is a coil of wire with many turns. A coil is strictly one rotation of a wire, however a solenoid would not be formed until a significant number of turns have been made.

@picketf 6 жыл бұрын

solenoids are coils that contract an object through an electromagnetic field. Coils however have many different functions and uses not limited to solenoids. For instance a typical electromotor has coils that rotate in an electrically charged tunnel. In bigger motors these coils are shielded through copper plates that also act as mechanical bearings to reduce friction in the shaft. On smaller electromotors for RC toys these plates are often missing and bare coil spools can be found in the center of the motor. Coils can also be used as induction coils to drive up the higher currents needed by camera flashlights.
