Read Superman's page on the wiki.

Yeah, I myself recommend you to follow whatever it is on the wiki. Read with caution for better understanding and memorizing the highlighted statements you need to know.

In case if have not found it yet

Weaknesses include:

1) Kryptonian Physiology: Under the effects of "yellow" sun, Superman possesses the same potential weaknesses as an average Kryptonian. These include:

• Vulnerability to Kryptonite

• Vulnerability to Majic

2) Solar Energy Dependancy: Kryptonian abilities will eventually weaken without replenishing their energy reserves with normal [yellow] sun radiation. When exposed to the same red solar radiation as Krypton's red sun Rao, it causes Kryptonians to lose their powers within a large amount of exposure until exposure to yellow sunlight reverses this effect.

When exposed to orange solar radiation from a different galaxy, Superman's strength and abilities will drastically diminished, eventually weakening him. The radiation also affects his intellectual capacity and reduces his ability to think.

3) Sensory Overload: With his extremely acute senses, Superman can be overtaxed to the point of pain when encountered by extreme external stimuli such as hypersonics [hearing], balance, sight [flash bang].

4) Radiation Poisoning: [formerly] Superman was exposed to deadly radiation during his encounter with the aliens from the Breach, causing him to rapidly age. He slowed the progression of his condition via regular infusions of rejuvenating magic from The Enchantress, but this was undone by a sorceress working for Mongul. He was eventually cured by Genesis.

• Power Limitations: [formerly] Superman's sickness caused his powers to fade and weaken. While still significantly stronger than a human, he was less powerful than an average healthy Kryptonian until his radiation poisoning was cured.

What about electricity though?

Never heard of that actually 🤔

Well, to let you all know, I did check the superman page a long time ago, I got a superman book with 2 pages on this stuff and I go onto cbr and screenrant, it says nuclear weapons and electricity is capable of weakening superman and also saying superman is vulnerable to psychic attacks and can only survive in space or exercises for short time, let's say about a guess, um, few days. And what about lead, that's obviously something that can blind superman. and how about telling me about the different kryptonite how gold kryptonite can permanently strip superman's powers away and can somehow kill if made in bomb or knife. It sounds like you need more research and try to go beyond then this website, just saying.

Don't be a sheep. Do your own research guys.

Well, that was my first recommendation though 😗🙄

“It sounds like you need more research and try to go beyond then this website, just saying.”

How many Superman comics have you read firsthand? That’s the only research that truly matters. Even if the information here is cited you should still read that story yourself as people can still interpret things differently. You spout esoterica from clickbait websites that don’t even use citations and you have the audacity to imply we need to do better research?

Just saying.

Good point, it not only me, but the others are saying read it from this site, so I agree with you. people should actually read comics and tell me from their memories.
