Question 1

Faraday’s Law

Answer 1

states the voltage induce in a coil by a reaction of a magnetic field is directly proportional to the rate-of-charge of flux and the number of turns(of the conductor) and inversely proportional tot the change in time

Question 2

Lenz’s Law

Answer 2

the polarity of an induced voltage is always in a direction as to establish a current that opposes the current that caused it

Question 3

Inductance

Answer 3

property of a circuit that opposes change in current

Question 4

A Henry(H)

Answer 4

a circuit is said to have one Henry when a change in current of one ampere/per second induces an EMF of one volt

Question 5

Mutual Inductance (M)

Answer 5

when two coils are brought into proximity of each other, such that the lines of flux from one coil cut the turns of the other. Two coils have a MI of 1 Henry when an EMF of 1V is induced in a coil by the current changing at a rate of one ampere per second in the other coil

Question 6

Coefficient of coupling(k)

Answer 6

ratio of the actual number of lines of flux cutting the THEORETICAL number that could possibly cut the winding’s
