Electrical current, zapping & sparks
Not so much for the “kkzzr” but more for the “crkck”, try sticking various long strands of industrial strength packing tape to a firmly mounted window, and experiment with pulling it off in a way that causes a krk-krk-krk-krk stuttering effect. (The window amplifies the effect nicely).

1. high-pass a noise generator @ 8K and attach a random LFO to amplitude. 2. high-pass a recording of sizzling bacon. 3. record the sound of shooting a spray gun at a hot iron for sizzle fx. 4. sequence random splotches of high-passed turntable scratches. 5. twist up cellophane and high pass it. 6. scratch up nylon material and record it close mic’d. eq to taste.

Do you have an Ionic Breeze or equivalent air purifier? Try letting it go for 4-6 weeks without cleaning, and you’ll start getting some really nasty arcing from all the dust accumulation on the plates and wires. If you have a high-res mic (50k freq-response) and a 96k recorder, you can pitch it down an octave or 2 for some really big arcs and zaps.

Try (squeezing) some steel wool. Also you can try steel wool soaked in some salt water… Just a little.

Whip a porcelain sink or bath tub with a small metal chain (like the one attached to the sink plug). Then add distortion to the recording.

BE *VERY* CAREFUL WITH THESE!
Electrical hum / buzzing effect can be created with an electric condenser where the diaphragm has been removed exposing the FET.

If you take the hot lead of a line (or mic) in (bare wire works best but tip of a 1/4″ works also) and touch it lightly to various metal surfaces you can get some great arc sounds. Of course they are completely dry so you should put some reverb on them.

The way I learned to create “electric sparks kind of sound effects” was by an accident. Was in a summer. I was playing my electric guitar (unplugged) and in front of me I had a fan. So I moved to the right, don’t remember for what, and one of the strings, I think the 1st, the E, entered the fan. I mean, the leftover string in the headstock entered the fan because It was very long. And was music to my ears, because a beautiful electric kind of sound came out from that interaction. Recording this will give you amazing electric sparks and electric movements. And with further processing, for example using a transient designer, you can create a more complex electric sound. Just be careful when recording!!!

Electric welding works well too.

If you need some sounds to work from, you can give Dave Fienup’s Sci-Fi electric library a try.
