What current flows after a momentary voltage?

While there is a voltage, a current will flow - assuming there is a conducting path. The amount of the current can be calculated by Ohm's Law. That is, you divide voltage by resistance.


What is the function of the time delay Fuse?

The time delay fuse allows a momentary overload due to startup current.


What is the current rating of T2L 250v fuse?

The current rating is 2A (2 amps).


What is the maximum current that can flow through a fuse?

A current rating of a fuse is designed to open a circuit at a specific current flow. This rating is imprinted on the fuse and lets you know what the maximum amount of current the fuse is designed to open at. A fuse is in the circuit to protect the conductor that the current flows through. Never over fuse a conductor's current carrying capacity.


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.

How do you compute wattage?

Wattage or power rating of a product can be calculated by multiplying voltage rating and current rating. (Power = Voltage x Current). e.g. if device is working at 12V and 2A is the current rating. It is 24Watt. Since Voltage = Current x Resistance , for a resistive load power can also be calculated by Power = Current x Current x Resistance = I^2 x R = I square R


What is a fuse rating?

Fuses have two basic ratings. The first is current rating. The current rating is the amount of current that a fuse will safely pass before blowing. When the current flow through a fuse exceeds its rating, it opens up and breaks the circuit. If a fuse has a 5 A rating, it will open as current flow through it exceeds 5 amps. It is useful to note that there are some fuses that are designated as time delay. These fuses will sustain current in excess to their current rating for a short period before blowing. The fuse that blows immediately when its rated current is exceeded is an instantaneous fuse. The other way fuses are rated is by voltage. So when selecting a fuse, be sure that both the current and voltage rating are suitable for the application.Fuse rating is the permissible minimal current to pass in the fuse element,without causing the fuse to blow or melt.
