Voltage rating usually refers to the insulation of the wire but could be terminology for electrical equipment also. In North America standard voltage ratings of wire are 300, 600, 1000, 5Kv, 15 Kv and 25 Kv.

Does a high rating mean lots of insulation or little insulation?
It depends what you mean by a 'high rating'!If you mean a high 'voltage rating' then, yes, you will require thicker insulation. But if you mean a high 'power rating', then, not necessarily, because the voltage can be low, while the current is high.Remember, the thickness of insulation depends on the voltage, while the type of insulation (how it withstands higher temperatures) depends on the current.
What battery stack do I need for a device that uses 10.8 to 26.4 volts at 260mA maximum consumption to run for a minimum of two hours?
A battery of the correct voltage and at least 520mAH rating.
What happens if you use a fuse that's overrated for voltage but has the correct current rating?
Using a fuse correctly rated for current but "overrated" for voltage does not present a problem. Current ratings are critical safety issues, and fuses should be replaced with those of the same current rating. But using a fuse with an identical current rating but a higher voltage rating is not a problem. The reason for that lies in what the voltage rating of a fuse is. Fuses are given a voltage rating to state a maximum voltage in a circuit that they are designed to protect. And the voltage rating has nothing to do with the "normal" operation of the fuse. The fuse carries current when it operates normally, but when something happens and excessive current flows, the fusible link heats up and opens. This is where the voltage rating comes into play. It is possible that a fuse can arc through when it fails. It is the voltage rating that stands in the way of this. As long as the voltage rating of a circuit is not beyond the voltage rating of the fuse, that fuse will fail safely when it fails. It is acceptable to use a fuse of an equal current rating but a higher voltage rating when replacing a fuse that has failed.
What is Meaning of diode rating?
There are two diode ratings. One is the forward current rating, and the other is the reverse breakdown voltage rating. The forward current rating is the maximum current that the diode can conduct before failing, and the reverse breakdown voltage rating is the maximum reverse voltage that can be applied before failing. Of course, the reverse voltage rating has a different meaning in a zener diode, but this answer applies to ordinary diodes.
Why is voltage rating of a capacitor important to the user?
The voltage rating of a capacitor tells the user how much voltage the capacitor can withstand. If a user exceeds this voltage, the capacitor's dielectric may be damaged and destroyed.
Does a bigger sized battery have a greater voltage?
A larger voltage rating: yes, of course. A larger size rating: these are not normally related to the voltage rating, which is separate. A larger physical size: normally this means a greater voltage, but again, they are not directly related to the voltage rating. Size has nothing to do with voltage. Battery voltage is controlled by the number of cells in the battery. Plate size affects current delivery.
How long will a 1 watt bulb operate on a 1 amp hour battery?
Please give the voltage and Ah rating of the battery and voltage rating of bulb.
How do you troubleshoot a cmos battery?
Test the voltage of the battery. if the voltage is below the rating of a new battery (For a CR203 it would be 3.6 volts) it is defective.
Why some time the terminal voltage of a battery increases more than its rating?
When the alternator starts charging the battery voltage will increase about two volts to charge the battery.
What is mAH for battery?
The mAh for a battery is the rating to express the available current at the rate voltage for one hour.
What is battery mah?
The mAh for a battery is the rating to express the available current at the rate voltage for one hour.
Can you use a high voltage capacitor on a low voltage battery?
Yes. You just don't want to exceed the voltage rating of the capacitor.
Does higher voltage mean longer battery life?
Yes The larger the battery, the more voltage the battery has.
What does the voltage of a batter mean?
Do you mean 'battery'
Can a 3 volt battery light 5 leds?
It depend on what the rating voltage of the LEDs are.
What is the voltage rating of screw-guns?
In North America, if the screw gun plugs into a wall receptacle the voltage will be 120 volts. If it is a battery operated screw gun the voltage will be marked on the battery that operates the device.
How long can a battery power a 44 watt light bulb?
To answer this question the amp hour rating of the battery is needed along with the voltage of the battery or bulb.
