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.


How does electricity change from one transformer to another?

voltage gets smaller


What is s device that interferes with the flow of an electrical charge?

You cannot 'slow' the flow of current in a wire. What you can do, however, is to reduce its value, or to limit its upper value. The device that will do this is a resistor. If, by your question, you are asking how to reduce the rate of change in its magnitude, then you can use an inductor.


How do you change 115v to 230v?

You need to use a 2:1 ratio transformer, with a capacity (in volt amperes) to match the load you have in mind.


How do you convert 120 VAC to 120 VDC?

Of course you can! A transformer can change the voltage from 120 to 36. A rectifier can turn AC into DC. If you need constant voltage, capacitors to regulate flow can be added.

What size resistor to change 12 volts to 3 volts for a led?

Assuming that you're talking about 12V DC you would use a 4 ohm resistor. If you mean AC then you would need a step-down transformer with a 4:1 ratio.


The basic function of a transformer is to change?

The basic function of a transformer is to change voltage levels.


Why is a transformer necessary?

A transformer is not 'necessary'. The human race evolved, and developed cultures, societies, disease resistance, and technology, without ever seeing a transformer. But there are specific situations in which desirable things can be accomplished much more effectively and efficiently with a transformer than with any other device or method. Here are a couple of examples: -- If the voltage you have available is not the voltage you need, then you can use a transformer to make the change. (But that only works for AC.) -- You can use a transformer to change the output impedance of an amplifier to the impedance of the speaker or earbuds you want to use with it.


You can use neutral to autotransformer?

Yes, but the transformer must have both the hot and neutral to work as designed. A auto-transformer is not a variable resistor that could reduce current/voltage by a change in the resistance which could be used in the hot and or neutral wire. An auto-transformer is designed to have the hot wire and neutral on each end of the winding with a variable tap in between. The resistance of the transformer and the inductance will effect the circuit to a limited way if placed in the neutral but this effect will not vary the voltage over the full range, the amount of voltage reduction will vary with the load's current draw, see ohms law. Neither a resistor or a auto-transformer connected in the neutral line only will increase the voltage above the level of the input like a correctly connected auto-transformer . Stanley


Difference between variable and fixed resistor?

Variable resistors means that a resistor which can change its resistance by control by any person or it self and fixed resistor means that it can not change its value.


How you change the blower motor resistor in Nissan maxima 2002?

To change the blower motor resistor in a 2002 Nissan Maxima, locate the blower motor resistor under the glove compartment on the passenger side of the vehicle. There is a clip that is depressed and then the resistor will slide out. Remove both ends of the resistor and then replace with the new resistor.


Can a transformer change into anything?

Yes it can


How do you make ac into DC in a ac transformer?

You can not change AC into DC using a transformer. A transformer changes the voltage levels. To change AC into DC, you would need a rectifier. To change that into smooth DC you need a capaciter and a voltage regulater

Function of a variable resistor?

Variable resistor is an resistor that can change its resistance manually, by rotating a handle or a screw.


What is the purpose of constant voltage transformer?

The term 'constant voltage transformer' is used to differentiate the operation of transformers that are intended to change voltage levels, from those intended to change current levels -a current transformer (CT), for example, is termed a 'constant current transformer'.
