Is it normal to have spark inside the infinite switch in electric range stove?
A spark is not a problem. What you are seeing is the points making a connection. When you first turn on the infinite heat switch, a bi metal strip is heated through an electrical coil which then causes the bi metal strip to bend and make contact with a stationary contact which then sends the 220 V to the element. This coil cycles on and off causing the bi metal strip to straighten and break the connection before bending and reconnecting.
My space heater sparks on the inside?
I've had two space heaters do this. The second one just did and the 1st one 6 months ago. There's no power in my room and I get all my power from an extension cord that goes to the hallway. There's a power strip plugged into the extension cord. And another shorted extension cord plugged into the power strip. My tv and cable are plugged into the shorter extension cord and I have the lamp and one more extension cord that powers my phone charger plugged into the power strip. I don't think there's anything wrong with the heaters but maybe they got overpowered? The outlets don't spark but the inside of the heater does. Inside the vents. There's no heat in my room at all and I freeze nightly plus I'm 5 months pregnant. No money for an electrician and I'm the only one that has no heat.
I saw Sparks coming from my Alternator when i left it running in Parking Lot, what does this mean?
now binky let me give you the low down here. if a person wished to they could see the brushes and windings doing what they do, making electricity. some tiny sparking is often visible from within, tiny! big sparks are totally different this could be an alternator going bad. if strange gringing sounds are present as well then its a bad condition. by the way have you weened binky from the troll diet yet.
Is it safe to continue to use a surge protector after a large spark upon plug-in?
Sorry.. I don't usually answer this way, but Ner's answer is completely wrong. The thing is, you didn't get a "surge" in the first place - not the kind a surge protector protects against, anyway.] What you got was either an intermittent connection in the outlet, or an intermittent short circuit in the outlet - probably the latter from the description. Either of these will result in the voltage at the outlet, seen by the surge protector, "stuttering" between 0 and the usual 120 volts. (240 volts if you're in a "240:" country.) A "surge" of the sort that surge protectors work on, is something very different. It is *excess* voltage in the line. And the MOVs (the active components) in a surge protector don't start reacting until a relatively high voltage, typically 300 volts or more! (600 volts or more if you're in a "240" country.) These surges are usually the result of problems upstream on the power lines. There is no way that either an intermittent "hot" connection, or an intermittent short between hot and ground or neutral, in your outlet is going to drive the voltage that high. Or any higher than line voltage, in fact. So your "surge protector" never actually saw a "surge" in the first place. So it's fine. By the way, it is also safe to use a surge protector after it HAS been hit by a surge - its kind of surge. Every surge handled by the MOVs takes a little bit out of them, but one surge isn't going to make the SP useless. Most SPs have an LED that normally glows, and stops glowing once the SP's protection has been worn away. And the SP is still safe to use after that, electrically speaking. It can be used safely as an ordinary power strip. It just won't protect against surges. The outlet, on the other hand... is not safe. You should immediately turn off the circuit breaker that supplies that outlet, and demand that your landlord repair it. It might start a fire and kill you (literally) at any time (unless of course you have the breaker turned off). It is flatly not legal for your landlord to rent the apartment to you until this is fixed.
My washing machine sparks inside the timer dial itself?
You don't need to replace the washer. The timer might need replacing. My dad was a repairman. He has rebuilt these before too. A new timer can run you as little as $30 but as much as $150. It depends on your options and the brand and if you get a generic part or a direct replacement. They are not that hard to replace, if you are handy, but if not, just let a repairman do it, then the work is under warranty (reputable ones warranty their work).
My blow dryer sparked... Should I use it?
While my sister was drying her softball uniform with my blow dryer (weird, I know, but we were out of town and didn't have a dryer), a spark came out of it. It came out of the part that air comes out of. Can I still use my blow dryer? Is it going to spark again? Can I fix it?
What would cause a spark to occur in midair?
Something as simple as dust floating in the air, if all the conditions are right, could set up an electrostatic charge that could discharge in midair. That's precisely how lightning works, and some lightning strikes do occur in midair (up high, of course). (BTW, lightning does occur in dust storms too.) However, there must be something capable of holding the charge, like a cloud or something conductive. Two things actually -- one holding the negative charge and the other the positive charge. In your case, however, considering the strengh of the discharge as judged by the loudness of the spark, and the fact that it occured during a thunderstorm, I think it is much more likely that a nearby power line was struck by lightning and that some of the charge entered your house through the wiring. You may one day find a pinhole in the wall where the spark entered the room from the wiring. And another hole where it exited to a water pipe or some other conductive path to earth ground.
