100 v DC is not the same as 100v AC the AC will be 141v which can arc over the contact if rated as 100 v DC.
The deal is that when switches open and close they arc for a short period of time. This is the main factor in wearing out the switch. Because AC automatically alternates back and forth, the arc is naturally extinguished faster. The DC, however, sustains the arc until the switch gap is large enough to shut it down. Therefore, the DC ratings must be lower to provide the same switch life and reliability.
making current is a peak value attain at first cycle when the circuit breaker is close.the making current rating is expressed in "peak" value of the maximum ac current it can safely close on that's why it is always have higher value than breaking current. Making current is limited by the withstand capability of the contacts. Breaking current is based on the ability of the contacts to interrupt the current. If the contacts are not able to interrupt the current when they open, the heat energy in the resulting arc will often destroy the device. the breaking current rating is expressed in RMS value of the current.

It depends on the voltage rating.
A zener diode with a rating of 500 mW will pass 50 mA at 10 V. (Power = voltage times current)Note: The question appears mis stated, in that it states a rating of 500 MW, not 500 mW. To my knowledge, there is no zener with a rating of 500 MW.
Divide the output rating by the input rating
The typical rating of a hot wire relay contacts is 35 amp
The typical rating of a hot wire relay contacts is 35 amp
Awsome Axe Approach
On the side of the relay there is a name plate that tells you the current carrying capacity of the contacts. It gives you the ratings at different AC voltages and a DC rating of the contacts at different voltages.
The current ratings of the contacts of a relay are written on the side of the protective envelope that covers the contacts.
No. Your rating stops at 9999, but your knowledge can go on forever.

Theoretical winds for an F6 tornado are 319-379 mph. However, because tornado ratings are based on damage, the highest a tornado could ever be rated is F5. So the F6 rating is purely theoretical with no applications in the real world. On the enhanced scale there is no EF6 level theoretical or otherwise.
As a general rule, the larger the current rating of the fuse, the larger will be the fuse holder (or at least the metal contacts) because it will have to be capable of handling larger currents without overheating.
There are theoretical categories beyond F5 but none of theme have ever been used. Since F5 damage is total destruction there is no real way of rating a tornado higher than F5. Also, a tornado's rating is not dependent on its size. So a bigger tornado does not necessarily get a higher rating.
No. If you use a larger fuse you are not protecting the device which has a rating of a lesser value.
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.
