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(

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

it's ok :")

alternating current will flow through the primary coil
YumYum247
  • YumYum247
just like the DC?
rvc
  • rvc
then according to faradays law an emf will be produced
rvc
  • rvc
i dont understand how DC will help
YumYum247
  • YumYum247
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....
rvc
  • rvc
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
YumYum247
  • YumYum247
OH and let me guess..... the second way would be to use a magnet????
rvc
  • rvc
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

lets ask @ganeshie8

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

he will
YumYum247

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

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

Lol you can start off by closing the switch xD
rvc
  • rvc
lol
YumYum247
  • YumYum247
with my potential or kinetic energy??
Astrophysics
  • Astrophysics
What?
rvc
  • rvc
dc supply
Agl202
  • Agl202
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.
Astrophysics
  • Astrophysics
^ that sounds good to me!
YumYum247
  • YumYum247
nvm proceed plz.
Agl202
  • Agl202
Second...lemee think
YumYum247
  • YumYum247
but i need two ways!!!
YumYum247
  • YumYum247
battery?
YumYum247
  • YumYum247
for Dc
YumYum247
  • YumYum247
what about AC current
Astrophysics
  • Astrophysics
Same reason agl gave you
Agl202
  • Agl202
For second one, try it with the switch on.
Astrophysics
  • Astrophysics
The magnetic field will be changing continuously
YumYum247
  • YumYum247
so to continuesly light the bulb...i need to open and close????the switch

we have 5 peeps here, how should we distribute medals so that everyoene has one???
YumYum247

astro you ruined it.... goodnoght

It's ok medals don't really matter haha

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

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

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 \(T\)

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