MagSafe Power Adapter 85watts has exploded. Electrical scheme is needed

Its a varistor, not capasitor, so the problem is bigger. Red fuse(i guess) belong is also broken.

People are answering you. They are telling you to call Apple and get a replacement for free. It's not worth fixing yourself simply because it's so easy to get another one for free. Apple is very accommodating with their replacement cords especially when they fail in a potentially dangerous manner.
Was that a fault in hour house wiring, lightning strike or something else? (Just curious).
I would say in case of a lightning strike, the primary design goal for a power supply wouldn't be to survive in working condition, but to protect whatever is attached to it, like an expensive MBP, and not let anything through that the attached device cannot handle. Worst case is probably a MacBook with the battery removed; that probably couldn't handle much more than the normal voltage from the power supply.
If you have an Apple Store nearby, you might as well take it there and try your luck. I am sure they _can_ replace it for free, even though they don't have to. Good people skills might be required as usual. If you tell them you are going to repair it they'll probably give you a free one instead of risking that you kill yourself
IMHO... If you can't identify the component in a switching power supply, you probably shouldn't be randomly replacing components in the hopes your going to fix it. Looks like a cap, but could also be a MOV.
Anyhow, you should be trouble shooting it first, even without a schematic handy (all switching power supplies are basically the built on the same block design). You could do some basic component testing with a multimeter before hand.
Our just buy a new one. That failure looks early on in the power supply stage, I'd suggest a HV spike took it out.
