A 4700ohms resistor rated as 5watts find out it maximum safe working current?
Power dissipated = I2 RI = sqrt( P/R ) = sqrt(5/4,700) = 32.6 mA . (rounded)Note:It's only "safe" if the power actually dissipates, i.e. doesn't just hang around the resistor.32.6 mA is 'safe' if the resistor is heat-sinked, or at least out in the open air. It's not safeif the resistor is wrapped in a cozy blanket.
Why rheostats have current rating in addition to resistance rating?
A resistor, of which a rheostat is, has a maximum amount of current it can handle. Beyond that value it will start heating up a lot and might burns up. Since, the maximum resistance of a rheostat is fixed so does its maximum safe current value that can flow through it.Comment'Rheostats' and 'potentiometers' describe applications of variable resistors; they are not alternative words for variable resistors.
What is the recommended maximum safe voltage for outdoor uses in Europe?
In Norway it is 230 Volts, 16-25 amp, 60 Hz, grounded In rest of Europe it is 110 Volts 10-15 amps, 50 Hz, probably grounded too.

1. Safe. Always the first thing. 2. Good speed and elements a.k.a Loops 3. Good G forces.
What is the name of the most dangerous roller coaster?
That's a stupid question. Roller coasters are very safe. None can be considered "most dangerous"
Why was the first roller coaster built?
To build potential energy, which is converted to kinetic energy upon descent. The higher up the roller coaster climbs, the more potential energy it builds, thus having more kinetic energy upon descent. Since there are no motors or engines, roller coasters are reliant on this back & forth transfer of energy.
Is the big roller coaster at Oaks Park scary?
You mean Looping Thunder? I don't get scared of roller coasters. But for someone who is new to them, yes. But I Garuntee the ride is safe.
What are the early disasters of roller coasters?
Modern roller coasters are quite safe; they have many checks and are monitored often to ensure they remain safe. However, ride accidents do occur. People who aren't riding can be hit by the coaster if they enter the coaster area. As well, people who are too small can fall out of the ride if they aren't secured safely.
Chances of fainting a roller coaster?
A little less than 10%, roller coasters are safe, if you are nervous. They do checks along the track and on the machinery before a park opens every day.
Are Six Flags amusement parks safe?
Six flags is only safe if you don't do stunts on the roller coasters like standing up, other then that six flags is fun and safe. By the way when your going down on a roller coaster sticking your hands up does not count as a stunt.
At what point in your pregnancy can you not ride a roller coaster what if you are only a month pregnant?
don't ride a roller coaster if you are pregnant. Doesn't matter how far along!! Probably nothing would happen and you would be quite safe at least until 3 months, but if anything did happen you would blame yourself.
Why are roller coasters so safe?
Because of the way they are engineered to keep a person on the rollar coaster ,and because most of the coasters are inspected and tested and all that
Can you ride a roller coaster at 7 weeks pregnant?
I would not recommend riding a roller coaster. The force of a roller coaster is almost the same as the one that astronauts experience on a rocket. Plus you will probably squish your belly in the safety seat or you may not be able to pull it down far enough to be safe. A merry-go-round or a Ferris wheel are safe to ride on.
