Tell me what car the fuel tank is located in and I will tell you the fuel capacity.
Using a transformer with a higher capacity that is needed by the device connected to it will not damage the device. This is as long as the voltage the device needs is the same as the transformers output.

Rom that is read only memory can be erased by large voltage because every electronic device have own system which means that are made to process or work within there capacity. for example a man cannot eat more than there capacity ,if they do they fell uncomfortable similarly if more voltage is provided to computer [more than there capacity] than it will be crash.
A device that wants to be supplied with 4v, will be destroyed if connected to 12v. Do not confuse voltage with Amp/Hour capacity, which is what I think you are looking for. Make sure the voltage matches the device. Then determine how much current the device draws. The power supply will be rated as to how much current it can deliver and for how long.
A rectifier is an electronic device that changes an AC voltage to a DC voltage.
the device oprates on the minimum voltage. in this voltage is called threshold voltage.
the voltage at which electronic device operates is callled threshold voltageand the voltage at which device show cinduction in forward biased stste
-- Apply a small, known voltage between the terminals of the device. -- Measure the current through the device with the voltage applied. -- Calculate the resistance of the device. It's (voltage) divided by (current).
Do a voltage test. Start at one end of the circuit and progress along device by device. If there is voltage on the down stream side of the device move on to the next. If there is no voltage on the down stream side of the device then go up stream of the device. If you have voltage there then the current device that you are at is the problem causing an open or broken circuit.
The difference between a current control device and voltage controlled device is that for current controlled device, the current is constant and the voltage is variable while for a voltage controlled device, the voltage is constant and the current is variable.
As long as the source voltage power supplies capacity is larger than the device's demand then it can be used.
No, twice the voltage applied to a device that only requires 6 volts will probably destroy the device. When a manufacturer of equipment states a required voltage for a device that is the voltage that must be used.
