Why does a regular phone still work when there is a power failure?

because it's a voltage that carries the phone signal on it, and that's what your phone runs off - unless it's one that also has a power connection - ie cordless, memory bank etc etc

Can a phone system be plugged into same wall outlet as ups?
If your phone system is a PBX then yes you can plug it on the same outlet where a UPS is plugged. You can even plug your PBX system to the UPS so when there's a power failure you can still have few minutes source to power your phone system.

What happens when the power goes off while charging a mobile phone will the battery go dry if its still plugged in even after the power if off?
No, it won't. Basically, plugs are one-way streets. Electricity frow out of them, but you can't "charge the power company." So the phone can charge, but if the power goes out, and it's still plugged in, it won't discharge any faster than normal, since the power has no where to go except to power the phone.
With regular batteries will solar light still charge?
Regular batteries will power a solar light until they run out of power. But regular batteries can't be charged from the solar cells unless rechargeable batteries are used instead. There is also a bit of circuitry involved.
What happens when your phone is about to kill off can you still send texts?
Only for as long as there is enough battery power for the phone to complete the send function.
Does the car charger draw juice if the car cell phone is not attached?
It depends on the car. Some vehicles shut off power to the lighter port when the ignition is not cranked. Others do not. If your car still allows power to the port, then the charger will still draw from it, phone plugged in or not.

That depends ! If the electrical system still supplies power to the socket you plug the phone into - then yes, it will charge. If not, then it won't !
Does the cell phone battery on if you turn phone off?
Even when a phone is off - it still uses a minute amount of power from the battery. It constantly checks the circuitry to see if the power button has been pressed. Even a fully-charged battery will eventually run down in a phone that's switched off.
Do phones go out when electricity does?
Maybe and maybe not. Mobile phones have their own batteries, so whether the electricity is on or not is largely irrelevant to the phone. Nearby towers may or may not be impacted, so even if the phone itself still works, it may not be possible to use it to make calls in the affected area. Home phones... it depends on the phone. Some phones (e.g. cordless phones) need mains power to work, and those will go out if the power does. However, some old-style corded phones draw all the power they need from the phone lines, which get power from the central office. If the central office still has power, this type of phone will still work (assuming the telephone lines aren't down as well). Even if the mains power is out at the central office, they generally have backup power systems (batteries and/or generators) to keep the phones working at least temporarily.
Do people still use compasses today?
Despite their many problems and odd behaviors, magnetic compasses are still part of every aircraft's instrument panel. Since they are not affected by power failure or any other type of system failure, they are still a vital backup instrument even though pilots now primarily use the gyro compass or GPS for navigation.
