What will happen if i connect a power supply of higher current rating to lower current load?

The supply won't have to work as hard. It is perfectly acceptable, for example, to use a 1A, 12v supply to supply a 12v, .5A load. The current rating indicates the ability of the supply to dissipate heat caused by the current flowing. If the load current is above the power supply current rating, the power supply will overheat.

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 will happen if higher rating capacitor is used in fan?
It will rotate faster.Since the fan is not designed for this, it will progressively ruin it.
When cells are connected in parallel then?
putting cells in series gives you a higher voltage but at the same current rating. putting cells in parallel gives you the same voltage but at a higher current rating. series parallel can give you both..
If your universal alternating current direct current adapter has more amperage than you need will that mess up your electronic product?
No, your universal alternating current direct current adapter will not mess up your electronic product. The rating that you find on the adapter is the maximum amount that you can draw from the device without damaging it. It is not like there is a surplus of current waiting to be used. The amount of current draw that it can produce is governed by the load demand. What you don't want to do is connect a device to the adapter that has a load higher that the rating of the adapter. Usually you can find the rating on the adapter rated in milli amps (ma) along with the output voltage. Also the load device will have what the amp draw is, also in milli amps.
How many amperes of current run through 440volts?
Depends on the rating of the source. For the same electrical load, a higher voltage will require lower current, but there's no specific current associated with 440V.
Is amperage rating and running amperage the same thing?
Usually the current rating for a circuit is higher than the current usually taken. This leaves a little margin for safety.
What way is used to connect batteries together to provide more current?
Connect them in parallel. They must be the same voltage and the same or similar amp-hour rating.
Is the current in the circuit 80 percent of the fuse rating?
It should be, yes. Never higher.
What will happen if less current rating fuse is connect to function generator?
By reducing the output fusing of a generator, the total output of the generator will also be reduced. The capacity of the generator will remain the same but the fault trip point will be lowered.
What could happen if a blown fuse were replaced with one that blew at a much higher current than the original?
The circuit or device that the fuse was meant to protect would not be protected if a fuse with a higher rating were to be used. This could result in the circuit or device being destroyed by a higher than normal current flow in a short circuit fault condition.

Which is the higher rating Google Plus or facebook?
For Now it's facebook.. But don't know what happen in future.

How do you connect 2 6 ohm speakers to an 8 ohm amplifier?
You can, but its power output will be a bit higher than its 8 ohm rating.

Will a circuit breaker give off less amperage?
A circuit breaker does not give off amperage. A circuit breaker allows a flow of current up to the rating of the breaker. Any current higher than that of the breaker's rating will open the breaker's contacts and stop the flow of current.
