Explanation / Answer
12). Electrons are forced to move to produce a small enmf in the solar panel.
Because due to motion of electrons current is produced.
14). In inductor voltage leads the current by a phase of 90 degree
Hence the statement is false.
16). By right hand thumb rule we can know the direction of magnetic field due to a current carrying wire.
17) emf can be produced by the Lenz law...when ever there is flux linkage with the coil changes then emf is Induced in the coil.
