Question 1

What is an inductor?

Answer 1

is apassiveelectrical componentthat stores energy in the form of amagnetic fieldwhenelectric currentflows through it

Question 2

What is inductance ?

Answer 2

tendency of an inductor to oppose the change in the electrical current flowing through it.

Question 3

What is the formula of the inductance?

Answer 3

L= NΦB/I

Question 4

What is the formula of the average emf ?

Answer 4

E= -NΔΦB/Δt

Question 5

What is the formula of the flux?

Answer 5

Φ=BAcosθ

Question 6

What is the formula of the voltage of the inductor?

Answer 6

VL=-E=L di/dt

Question 7

What is the formula of the intensity in the RL circuit while charging energy?

Answer 7

I=E/r(1-e^-t/tau)=io(1-e^-t/tau)

Question 8

What is the formula of tau in the RL circuit?

Answer 8

τ= L/R

Question 9

What function does the inductor resemble while charging energy?

Answer 9

It behaves like short circuit

Question 10

What is the formula of the current in the RL circuit while emptying the inductor’s energy?

Answer 10

I=E/R e^-t/tau

Question 11

what is the purpose of the inductor in the RL circuit?

Answer 11

the inductor delay the arriving of the current or the disappearing of it.
