Why should you use a fuse of proper rating in an electric circuit?

Because - if you use one that is too weak, it will 'blow' too quickly. If you use one that's too strong, excessive current could destroy the circuit before the fuse blows - possibly leading to a fire !

What electric element should be used so as to open the closed electric circuit?
which electric element should be used so as to open the closed electric circuit
What size amp circuit breaker should be used for a gas dryer?
Typical residential electric dryers are on 30 amp circuits, which means 10 gage copper wire. The circuit breaker should match the dryer cord rating, generally 30 amps.
Which electric element should be used so as to open the closed electric circuit?
A switch, circuit breaker, fuse, or switching transistor can do that.
Is the current in the circuit 80 percent of the fuse rating?
It should be, yes. Never higher.
What are the ratings of electric geyser?
The rating should be in watts and this information will be on the nameplate of the equipment.
What do fuses do?
Structure and use of a fuse: A fuse contains of a metal contact cap,glass casing,thin metal wire with a low melting point.When the electric appliances is faluty,the excess electric current will flow through the crcuit.Owing to the heating effect of elecric current,a large amount of heat will be produced.The circuit may thus occured a fire.The installation of fuse can stop excessive electric current.the low melting point thin wire in the fuse will melt and break the circuit in order to protect the electric appliances and prevent a fire.But fuse is quite unconvenient that after it's bruned out,you need to replace a new one. fuse rating: fuse rating refers to the amount of electric current that can flow through the fuse without melting the thin metal wire.The higher rating can provide larger electric current.We should choose a greater ampere fuse than the electric appliances in order to prevent the breaking of circuit when electric appliances are working normally. The similar appliances:Circuit Breaker The use of a circuit breaker is similar to a fuse.When an electric current increases suddening and exceeds the circuit breaker's raging,the circuit breaker will turn to"OFF" switch automatically and break the circuit in order to protect the electric appliances and prevent a fire.It's more convenient than a fuse cause you only need to turn to"ON"switch when reconnected.
On an 50A circuit should you be able to turn all of three of your electric heaters on at the same time without tripping the main breaker?
Check the amp rating of the heater and do the math. Electric heaters pull A LOT of current, so I'm guessing you'd be near the 50amp max.
What is used in an electric fuse?
That depends on the KW rating . You should consult a qualified electrician
What size amp circuit breaker should be used for a pool light?
The pool light is usually on a 15 amp circuit. The breaker feeding this circuit must have a GFCI rating.
What is the thyristor firing circuit?
The thyristor is basically used a switch in an AC circuit to control the amount of power fed to the load. To turn on this switch an "electric" pulse should be applied to the Gate terminal of the Thyristor. A circuit which supplies the "electric" pulse is called the firing circuit.
Can an electric razor with a proper bathroom adaptor be connected to the 5 amp circuit?
There should be no reason that it will not work as long as the razor draws less than 5 amps and that the voltage of the razor matches the supply voltage.
What fuse is used in an electric shower?
That depends on the KW rating . You should consult a qualified electrician
