Wizard 5 / Eldritch Knight 3 [duplicate]

I’m having trouble finding the answer to my exact question after extensive searching on here and other places. I am currently a Level 3 Wizard / Level 1 Fighter. I aim to focus on my wizard levels but I was thinking about taking Level 3 Fighter to gain access to the Eldritch Knight martial archetype. Basically what I want to know is will being an Eldritch Knight give me access to more spell slots outside of wizard spell slots alone? Also, will it enable me to learn more spells that I could not as a wizard only character. I hope this makes sense and thank you in advance for help. What I’m hoping to hear is something like wizard gives me 4 spell slots for level 1 and being Eldritch Knight gives me another 1/2 level 1 spell slots etc etc.
