Can you change the 1 amp fuse on a shaver adapter to a higher voltage so you can use it with something else?

Changing a fuse size does not change the voltage output. An adapter is a transformer. The transformer in this adapter has a set of turn ratios determined by the manufacturer to produce a specific secondary voltage when inputted with a specific voltage. You may be able to use the adapter on another device but it has to conform to the specifications of the adapter as it now stands.
The fuse protects the primary side of the adapters transformer so as to not overload the transformer. If the fuse is up sized then the risk of overloading the adapter becomes a possibility. This could burn the windings of the Transformers secondary and render the adapter useless.

Can a 12 volt 0.5 amp ac adapter substituted with a 7.5 volt 1 amp adapter?
No, it is not recommended to substitute a 12 volt 0.5 amp AC adapter with a 7.5 volt 1 amp adapter. The voltage and amperage ratings need to match the requirements of the device you are powering. Using a lower voltage adapter may not provide enough power, and using a higher voltage adapter can potentially damage the device.
Can you use a 12V power adapter on a device that requires a 6v adapter?
No, the voltage is too high by 25%. maybe. in many cases it will not work. However, some devices convert the input voltage to a lower internal voltage like 5V and then the higher voltage adapter may work. However, it could lead to other problems like overheating, so it is not a good idea. Many devices specify a range of input voltage
Can you use a 19v adapter on a 15v device?
In short: Yes. As long as the voltage is the same, it makes no difference if the rated current is higher on the supply than on the device you want to operate. If you would take a 1.5 amp adapter for a 2 amp device, you overload the adapter which results in shut down or failure.
Can I use a laptop ac adapter with the same volts but higher amps?
Yes. The current rating listed is the _maximum_ current that the power supply can provide without a drop in voltage.
Is a 10 amp power tool better than a 5 amp?
At the same voltage yes, as the higher voltage is an indicator of a higher horsepower.
Can a 5.3volt adapter be substituted for a 4.5 volt adapter?
No the higher voltage could damage the device connected to it.
Ac Adapter is it ok to use higher voltage?
On both the primary side and the secondary side the answer is no. It's OK if the voltage is within 10% of your original AC Adapter.

What are the advantages to having a higher wattage ac adapter for a notebook?
You should not use a power adapter with a higher voltage output than the input rating on the computer. It can cause damage to the computer and the battery. You can use a lower voltage. If you do and you are using your computer, it might not charge but it will prolong the time you have before it runs out. If you do not use it, then it will charge but slower than with the correctly rated power adapter.
Can you use 5v ac adapter instead of 4.5v ac adapter?
Yes the voltage is close enough to work. What you have to be cautious about is the milliamp output of the adapter. Make sure that the output of the adapter is higher than the device that plugs into it.
High voltage low amp adaptor I have the original power adapter for my laptop. The output rating for the ac adapter is 19v 3.42A. I have a replacement that has a 30v and 2.5A.Can i use it.?
NO!!!!! Find a charger with the same voltage!! If not, you will fry your battery. The only electrical number you can go higher on is the milliwats.
What components are used to change an AC voltage to a lower or higher value?
Step up transformers are used to increase the voltage to a higher value

Is it ok to use a 4.5v 800mA AC adapter for a device when the original adapter is supposed to be 4.5V 500mA - will it damage the device?
Yes. As long as the voltage is the same which it is. The 800mA is the capacity that the transformer can produce safely without going into an overload state. Your original adapter was rated at 500mA which means that what ever device was plugged into it draws less that 500mA. You might notice that the new adapter is slightly physically larger. So you are safe to use the new adapter with the higher rating.
Why is there change in terminal voltage as load applied to a three phase alternator?
The AVR (Automatic Voltage Regulator) control the DC field voltage to the rotor of the alternator, as soon as higher load is demanded from the alternator, the AVR output voltage go higher, hence, a higher AC voltage on the output of the alternator. If the voltage go to high then the AVR is faulty.
Conclusion of voltmeter?
The higher the resistance , the higher the voltage
The original 4V adapter that came with a cordless phone burned out. Can you use a 6V adapter instead?
With caution - yes. The higher voltage shouldn't cause any harm to the phone - due to circuitry built into the phone to 'smooth out' the voltage from the original charger. However - don't leave it connected for long periods once it's charged. It will take less time to charge the battery (due to the higher voltage). I've used 'replacement' chargers with phones in the past without any problems.
