Electromagnetic Induction and Alternating Current- Study material, IITJEE, NEET ,CBSE

Unit-4 Electromagnetic induction and alternating current

Chapter-1 Electromagnetic induction

Goals of study: By studying this chapter, you will learn

•The experimental evidence that a changing magnetic field induces an emf.
• How Faraday’s law relates the induced emf in a loop to the change in magnetic flux through the loop.
• How to determine the direction of an induced emf.
• How to calculate the emf induced in a conductor moving through a magnetic field.
• How a changing magnetic flux generates an electric field that is very different from that produced by an arrangement of charges.

Chapter 2 Alternating Current

Goals of study: By studying this chapter, you will learn

What is an alternating current and how it is measured.

How phasors make it easy to describe sinusoidally varying quantities.
• How to use reactance to describe the voltage across a circuit element that carries an alternating current.
• How to analyze an
L-R-C series circuit with a sinusoidal emf.
• What determines the amount of power flowing into or out of an alternating-current circuit.
• How an
L-R-C series circuit responds to sinusoidal emfs of
different frequencies.
• Why transformers are useful, and how they work. 

  How alternating current is produced by AC generator.
