first of all i am sorry because my first language is not english i have question please Give me an accurate answer. Suppose we have a wire 1 meter long if this wire to be complicated No longitudinal increments Will its resistance increase؟ |

I'm not sure I understand your question. What are we changing about the wire? Have you seen: $$R = \rho \frac {L} {A}$$ from https://ultimateelectronicsbook.com/resistance-and-ohms-law/#resistivity-in-ohmic-materials ? Where $\rho$ is a property of the material, $L$ is the length of the wire, $A$ is the cross-sectional area of the wire. In your question, which of these is changing? |

Does a flat wire have less resistance than a twisted wire?please answer me with yes or no thank a lot |

It's hard to understand your question so a yes or no answer is impossible. As long as the cross sectional area (A in mrobbins formula) is kept constant the wire cross section can be any shape (round, flat, square, twisted, etc.) and it will not affect the resistance for a given length and material.. |
