The voltage rating of a fuse (in this case 125V or 230V) defines the maximum circuit voltage that the fuse is safe to be used on. A fuse with a voltage rating of 125V should not be used in a circuit with a voltage greater than 125V. If a 125V fuse were installed in a 230V circuit and an overload current occurred, the fuse could explode.

A: THYRISTOR can be used to clamp damaging energy as opposed to a fuse that must blow open and invariably takes time to blow. A thyristor is much faster and controllable actually if the problem disappear it can be made to open up again and restore power for normal operation.
The formula you are looking for is Amps = Watts divided by Volts. Once you find the amperage you can decide as to the size of a fuse you should use. Remember that fusing protects the conductors of the circuit and not the load of the circuit. A #14 wire is rated at 15 amps and can legally be loaded only to 12 amps.
A relay is a switch; it is not usually meant to open under fault conditions (high current), and would likely fail if done so. A fuse is a fault protection device. If a short circuit develops, large currents will flow, and the fuse link will melt, causing the circuit to open. There are also protective relays, which are devices that sense fault, or other undesireable conditions, and are used to send trip commands to breakers.
no.. it could damage your electrical components.
No, the voltage rating should not be exceeded. However, you could use a 250v 10a fuse for a 125v 10a fuse.
It depends on what you are powering with the circuit, but probably not. The 1.5 amp fuse would blow in normal operation of the device.
No
yes. the 250v just means that's the maximum voltage rating the fuse can handle .. so it can def handle 125v. just not vice versa.
Yes, a 250V fuse can replace a 125V fuse if they have the same ampacity rating. The voltage rating is simply the maximum voltage that the fuse is capable of safely interrupting. You can go higher, but you can not go lower. Obviously, the form factor of the fuse must be the same, but that is often the case.
Use the correct fuse and nothing else.

There is no difference. Slo-Blo is just a trademarked name for a time delay fuse.
It is always best to replace with equal or higher rating. However, there may be applications where it would be fine, such as a low voltage circuit.
1 amp
No. If the voltage rating of a fuse is too low for the circuit in which it is fitted then, when the fuse operates (i.e. its link melts), the circuit voltage might maintain the resulting arc within the fuse, and it will fail to protect that circuit.
