1.	Ii) If the magnetic flux passing through a coil of 100 turns ofwire increases by 15 weber in 2 second. Find the e.m.f.induced in the coil. An electric bulb is marked as 240 V-60W. What does it mean?
Answer» DECREASE in the FLUX = 0.005 - 0 = 0.005 Weber, no of turns = 100 turns time = 5 s e.m.f induced = N × rate of increase of MAGNETIC flux = 100 ×× 0.005 / 5 • • • e.m.f induced e = 0.1 v = 100 mv..

Answer»

DECREASE in the FLUX = 0.005 - 0 = 0.005

Weber,

no of turns = 100 turns

time = 5 s

e.m.f induced = N × rate of increase of MAGNETIC flux

= 100 ×× 0.005 / 5

•

• • e.m.f induced e = 0.1 v = 100 mv..
