Why does dropout ruin my accuracy in CNN?

I've build a CNN in Tensorflow with 2 conv layers, 1 pool layer and 2 FC layers. When I don't use dropout I get 98% accuracy on training dataset and 90% on test dataset. But, when I do use dropout, I ...

Does dropout require multiple passes of the same data set, as a sort of ensemble method?

I'm a bit confused about dropout -- on one tutorial, it was described as basically an 'ensemble method' of sorts. This implies that you might need to create an ensemble of networks. Is this the case, ...
