No. The windings are set for 9vdc and will not step down to 5vdc.
No.
Most of the mobile phones have batteries of less than 5V rating, mostly up to 3.7V.Chargers are typically rated for less than 5V.Caution: It is not safe to charge these with a 9V charger. The battery may explode..
yes
To modify the input voltage to match the desired output voltage. Say you need 5V to operate TTL technology and you only have a 9V battery. You build an SCC change it from 9V to 5V.

No the voltage gap is too wide. If the higher voltage is used there is the possibility that the connected device might be destroyed.
No. In general, a charger needs to be able to figure out when the battery has reached full charge, otherwise the charger can damage the battery by overcharging it. You need to use the specific charger required for the battery. And, if you are trying to power a non-battery device that requires 1A from a 5V 100mA source, you will not be able to maintain 5V, so it will not work there either.
That's almost twice the voltage. The chances of frying your device is high.
No. Usually it's a -/+ 10% difference. So, a 9v would need at least 7.2 volts or more
It depends on the load. If there is no load, it will only draw the regulator's quiescent current, specified on the datasheet.
Voltage stabilizers are the circuits that are used to filter noise from the source voltage. DC voltage generated from a bridge network or diode network will contains voltage glitches. These glitches may cause serious problems to the operation of digital circuits. So a voltage regulator is used to filter these glitches. voltage stabilizer can be built using a voltage regulator ICs like 7805 for +5V, 7809 for +9V, 7905 for -5V, 7909 for -9V and so on.
Yes, the SterlingTek's Premium Fuji 5V Digital Camera Charger plugs right into the camera for charging and also adapts to fit any kind of socket worldwide.
