14. E B
Indunced emf depends on the rate of change of magnetic flux through the coil

15. Induced emf

17. DIRECTION ??? … of B produced…
The induced current produces magnetic fields which tend to OPPOSE the change in magnetic flux THAT INDUCES such currents

33. Alternating-Current Circuits
Faraday’s Law  The induced emf varies SINUSOIDALLY with time
 alternating current
 provide a source of AC power

34. Simple AC Circuit Purely Resistive Load (R) Purely Inductive Load (L)
Purely Capacitive Load (C)
