The quickest 1.6 coulombs can flow through a 8.5-A rated fuse is (in seconds, upto two decimal places):

Assertion:safety fuses are made up of materials having a low melting pointreason: safety fuses should be resistent to to electric current

what is the largest number of 1000W bulbs that can be connected to a 240V supply with a 5A fuse?

Formulate a relationship between the current rating of the fuse wire in a circuit and the amount of current the circuit can carry.

The diagram shows a fuse.Describe the action of the fuse in a circuit..........................................................................................................................

fuse or a circuit breaker may be used to protect the circuit.One type of circuit breaker is a Residual Current Circuit Breaker (RCCB).(a) (i) Use the correct answer from the box to complete the sentence.earth live neutralA fuse is connected in the ........................................... wire.(1)(ii) Use the correct answer from the box to complete the sentence.are bigger are cheaper react fasterRCCBs are sometimes preferred to fuses because they........................................... .(1)(iii) RCCBs operate by detecting a difference in the current between two wires.Use the correct answer from the box to complete the sentence.earth and live earth and neutral live and neutralThe two wires are the .............................................................................. wires.(1)(b) An RCCB contains an iron rocker and a coil.A student investigated how the force of attraction, between a coil and an iron rocker,varies with the current in the coil.She supported a coil vertically and connected it in an electrical circuit, part of whichis shown in the figure below .
