Question on understanding capital increase and reverse split

At $NKLA there are currently two things on the agenda: a capital increase to raise money and possibly a reverse split in order to be able to comply with the Nasdaq's $1 limit (if the share should fall below one dollar again after the current rally).

If I understand correctly, the capital increase will increase the company's share capital and the new shares must be issued at a price between par and the current share price. What would be the point of issuing shares at par? In theory, this is the share capital and may not be "touched". Theoretically, the company could only operate with the money above the par value, right? What about the value of the company? If new shares are subscribed, the issue price is determined by the value of the company. If I were to simply issue new shares, would the value of the company have to be redetermined and distributed over several shares, or could I simply issue new shares at a certain price? By doing so, I would simply increase my value of the company...doesn't make that much sense somehow.

The second question I have: How do a capital increase and a reverse split go together? In the one, I reduce the number of my shares and the value of my share increases according to the subscription ratio. In the case of the capital increase, however, I issue new shares and my old shares are diluted. Doesn't this pose a dilemma for Nikola?

Would appreciate your help in clearing up my thought chaos.
