A teacher was giving a lesson on the circulation of the blood. Trying to make the matter clearer, he said, "Now, boys, if I stood on my head the blood, as you know, would run into it, and I should turn red in the face."

"Yes, sir," the boys said.

"Then why is it that while I am standing upright in the ordinary position the blood doesn't run into my feet?" A little fellow at the back shouted, "Cause yer feet ain't empty."

There were three fathers to be in a hospital waiting room, waiting for their
babies to be born.

The first nurse comes out and tells the first father, "Congratulations
you're the father of two beautiful twins!"

Amazed, the man says, Great! I am the manager for the Minneasota Twins.

The second nurse comes out and tells the second father, "Congratulations
you're the father of three beautiful triplets!"

Amazed, he says, "That's cool I work for 3M."

All of a sudden, the third father opens the window and jumps out.

The third nurse comes out, and asks, "Where's the third father?"

One of the other fathers said, "Oh he jumped out the window.."

The nurse asks, "Why?"

He replied, "He works for Seven Up!"

n electric field is conservative ...

but the exception is induced electric field which is non conservative

A zoom lens is a mechanical assembly of lens elements with the ability to vary its focal length (and thus angle of view), as opposed to a fixed focal length (FFL) lens. They are commonly used with still, video, motion picture cameras, projectors, some binoculars, microscopes, telescopes, and other optical instruments.

hehee .... nice ...

n also electric field intensity between plates

= charge density (sigma) /permittivity

n permittivity of a medium > of vacuum/air.

therefore
electric field intensity between the plates of capacitor descreases on introducing insulating plate b/w the plates of capacitor

but induced electric field is non conservative

@ tarin

i think permittivity of a medium >of vacuum/air.

absolute permittivity of medium = k* permittivity of vaccum .......right ??

k >1

so permittivity of a medium >of vacuum/air.

m i right ??
