One orbital per C-H bond
Explanation:
The p-orbital involved in the C-H bond is co-planar with the empty p-orbital in the methyl carbocation. This geometry means that hyperconjugation can occur, with the electrons in the

The stabilisation is energetically favourable, because it results in the electrons in the

The C-C bond can rotate, so the carbocation can form stabilising interactions with multiple C-H bonds e.g. ethyl cation has 3 C-H bonds that can be involved in hyperconjugation.
