Yes. That is correct.

How do I write this correctly?

Dr. Frankenstein flung a power switch, blue streamers of static electricity crackled about the table the creature gave a grunt and opened smoldering eyes.

What you have is three sentences indicating a chain of action. Therefore you need to punctuate with semi-colons. Use a semi-colon after switch, and use another one after table. Then the sentence will work nicely.

Okay, like this?

Dr. Frankenstein flung a power switch; blue streamers of static electricity crackled about the table; the creature gave a grunt and opened smoldering eyes.

Yes, you have got it correct! Your revised sentence is punctuated correctly using semi-colons. It connects the three actions and makes it clear that they are all part of the same sequence. Well done!
