haha
U still didn't gave ur answer

exam r going

can anyone plz tell me how emi effect produces the output voltage in generators!
i know that when coil is moved, magnetic field lines r cut thus emf is produced but i want a detail answer!
plz help!

the ans for 8b) an alternating voltage is passed to the primary coil so there is a change of magnetic flux around the primary coil this is linked to the core, and the core links the secondary there is a change in the magnetic flux in the secondary coil thereby an induced emf is produced at the secondary coil

5a) solid : The molecules in the solid vibrate about their fixed positions. As the temperature increases the vibrations
are faster and occupy more space so the solid expands.

Gas: The molecules are spread far apart and moving randomly, so as temperature increases the movement is faster and
the molecules occupy more space.
