Question

1. What do you understand by the ' heating effect of current '?

2. What is an electric fuse? Explain the working of an electric fuse?

3. What is an electromagnet? Sate the various uses of an electromagnet?​

Answer 1

Answer:

1) The heating effect of electric current is widely used in our day-to-day life. ... When an electric current is passed through a conductor, it generates heat due to the hindrance caused by the conductor to the flowing current. The work done in overcoming the hindrance to the current generates heat in that conductor

2)An electric fuse is an electric device which interrupts the flow of current in an electric circuit. ... A fuse is usually a short piece of wire. The fuse is made up of a material which has high resistivity and low melting point, so that it melts down due to overheating of the wire during high current flow

3)Electromagnets are widely used as components of other electrical devices, such as motors, generators, electromechanical solenoids, relays, loudspeakers, hard disks, MRI machines, scientific instruments, and magnetic separation equipment.
