Question

kelp me please!!! X")
Can anyone physics me?!?!?!?

Answer 1

yes i can

Answer 2

know a direct current such as DC battery attached to the circuit 1 will generate electric field around to help circuit 2 to produce induced current to light the bulb but u don't know about AC current. X(

Answer 3

How does an alternating current going to turn circuit 2 work?

Answer 4

lol np :='''') 't was fun

Answer 5

theek hai.

Answer 6

sorry can'r help

Answer 7

can't

Answer 8

lol that is my next unit i don't even study yet

Answer 9

it's ok :")

Answer 10

alternating current will flow through the primary coil

Answer 11

just like the DC?

Answer 12

then according to faradays law an emf will be produced

Answer 13

i dont understand how DC will help

Answer 14

no i meant the question is asking to come up with two ways to turn the light bulb in circuit 2. so i thought the first way would be to attach a DC battery to the primary circuit....

Answer 15

change in current produces magnetic flux and therefore an emf is produced in the primary coil

the induced flux will also link to the secondary coil and due to the load present an emf will be generated so the light bulb will glow

Answer 16

OH and let me guess..... the second way would be to use a magnet????

Answer 17

when an alternating magnetic field is applied there will be current produced in the coil..
then the same way as above....

however im not sure of the second method since we are just making use of the other way lol of the law

Answer 18

lets ask @ganeshie8

Answer 19

don't bother.....he won't reply.

Answer 20

he will

Answer 21

you have better chances of getting a direct reply from a GOD than him. or at least he almost never reply to my tag.

Answer 22

you know i jus realized that the magnet won't work

Answer 23

he might be away from the keyboard otherwise he is always der when i tag him

Answer 24

luck you!!

Answer 25

y*

Answer 26

@Astrophysics :)

Answer 27

@Michele_Laino Master please come to my rescue!!!

Answer 28

heyy

Answer 29

yes :")

Answer 30

heya astro

Answer 31

Lol you can start off by closing the switch xD

Answer 32

lol

Answer 33

with my potential or kinetic energy??

Answer 34

What?

Answer 35

dc supply

Answer 36

First, U should close the switch before u do anything else. The increase in current will cause a magnetic field in the left coil. Also, The change in magnetic field will cause a current in the right coil and briefly light the bulb.

Answer 37

^ that sounds good to me!

Answer 38

nvm proceed plz.

Answer 39

Second...lemee think

Answer 40

but i need two ways!!!

Answer 41

battery?

Answer 42

for Dc

Answer 43

what about AC current

Answer 44

Same reason agl gave you

Answer 45

For second one, try it with the switch on.

Answer 46

The magnetic field will be changing continuously

Answer 47

so to continuesly light the bulb...i need to open and close????the switch

Answer 48

thats what i said above lol

Answer 49

astro

Answer 50

\[B = \frac{ \mu_0 I }{ 2\pi R }\] this huh what yeah

Answer 51

ok who should i give the medal to?

Answer 52

Me cause im the cutest

Answer 53

Give to astro! Plz and thx.

Answer 54

xD

Answer 55

how about we give each other some medal...to make everyone happy.

Answer 56

astro makeup an equation to satisfy the result

Answer 57

Haha what

Answer 58

we have 5 peeps here, how should we distribute medals so that everyoene has one???

Answer 59

astro you ruined it.... goodnoght

Answer 60

It's ok medals don't really matter haha

Answer 61

sorry :c

Answer 62

everytime....

Answer 63

>.<

Answer 64

LOve you, Buy AStro... stay cure!!!

Answer 65

lol @YumYum247
i believe that astro agl n me dont fight for medals like kids
anyways all the best :P

Answer 66

it was a joke love, don't take me seriously HUN.

Answer 67

sorry i you mind it.

Answer 68

awwie even im kidding dear :)

Answer 69

Let's suppose that at initial time the switch \(T\) is open, then in order to turn on the light bulb, we can close such switch \(T\). In so doing a change of magnetic flux concatenated with the primary coil is generated. Due to magnetic coupling, such magnetic flux change will be transmitted to the secondary coil, and, due to the electromagnetic induction phenomenon, a voltage drop will appear across the light bulb which will be turned on.

Similarly, if at initial time the switch \(T\) is closed, then we can note that the light bulb is off. Now, in order to turn on such light bulb, we can open the same switch \(T\). Again a change of magnetic flux will be generated into the primary coil, and again, due to the magnetic coupling, such magnetic flux change will be transmitted into the secondary coil. Now, due to the electromagnetic induction phenomenon, a voltage drop will appear across the light bulb, finally the light bulb will turn on.

As we can note, the working of the light bulb is possible thanks to the magnetic flux change into the secondary coil.
Now, we can get such magnetic flux change, if we replace the external DC battery, with an AC generator, since a generator provide a variable current, and then a variable magnetiic flux which is concatenated with the primary coil. Furthermore, using an AC generator, we can remove the same switch \(T\)

Answer 70

here is the same circuit which uses an AC generator, in place of the DC external battery:

Answer 71

Thank you master, i owe you my life!!!! Love you <3

Answer 72

Thanks for your appreciation to my work!! :) :) @YumYum247
