Darth Vader can not use force lighting, because of his severed arms. Robotic hands can't summon the force lighting. However Darth Vader can still use other forms of the force, such as force choke.
Why didn't Anakin use Force lightning against Obi Wan?
Anakin—in particular—was much more mature and powerful as Dooku had noted. He grew in power. He wasn't as reckless and impulsive anymore. He was very capable of defeating the old count, and Force lightning just wouldn't work on Anakin's fast-paced movements.
Force lightning ability was not restricted to dark-siders. Jedi and other light-siders who were strong of will and character could learn this power without falling to the dark side—but its use was viewed as inherently corrupting, and most Jedi Councils forbade its use.
Dooku first used Force lightning at a young age. According to the audiobook, Dooku: Jedi Lost, he was once abducted for a Dark Side ritual, conjuring lightning to kill his captors and escape. Dooku went on to become one of the greatest Jedi masters, but his ability to use lightning was seemingly a natural talent.

Though it's possible that he simply never had the knowledge to become a Force ghost – Star Wars: The Clone Wars and Obi-Wan Kenobi proved that retaining one's identity and consciousness after death was no easy task – it's equally possible that Kylo Ren could still return as a Force ghost, or as something else entirely, ...
Obi-Wan eventually left Anakin to the will of the Force when he realized that he could not kill Anakin because he was still a Jedi, and the Code prevented him from murdering a helpless man.
Out-of-universe, Hayden Christensen is mostly retired from acting and didn't want to do anything beyond his voice lines in The Rise of Skywalker. Originally Answered: Why doesn't the ghost of Anakin Skywalker talk to Kylo Ren, to make him stop what he is doing?
This is a rare problem for him to come up against, due to only other Sith commonly utilizing such a capability. However, in Return of the Jedi, the force lightning used by Emperor Palpatine is shown to be immediately and vitally debilitating to Darth Vader.
With his powers amplified by a Force dyad, Sidious unleashed a storm of Force lightning upon his enemies above Exegol. Although its use was officially forbidden by the Jedi Order for most of its history, light-siders like the Jedi could also use this power.
However, despite their strict adherence to the light side of the Force, several Jedi were known to use this power, as although it was considered a dark side ability, it was also a technique of telekinesis. Its use, however, was forbidden by the Jedi.
After his reincarnation, Darth Sidious aka Palpatine used a blue-bladed lightsaber when he fought Luke onboard his Super Star Destroyer Eclipse. Ultimately, Sith who wielded colors other than red were usually looking to disguise their dark affiliations.
In the construction of a Sith lightsaber, individuals partook in a process known as bleeding. By ways of the Force, they would pour negative emotions, such as rage, hate, fear, and pain into kyber crystals. The process would result in the crystals gaining a distinctive crimson or red hue.
He was fully in control of the fight when he was blasting Luke. Instead of trying to outright kill his enemy, Palpatine just used enough force lightning to torture him for his entertainment. Not only that, but Luke didn't have to endure it for as long as the Sith Lord.

After much meditation, Koon concluded that it would be wrong of him to ignore its power and that he should develop it into a useful technique. As requested by the Council, he recorded his experiences with the Force lightning that he dubbed "Electric Judgment" on the Great Holocron.
Yoda is a Jedi Master, and he's had centuries to perfect his skills. He's so attuned to the Force that he can channel it through his body, using it as a conductor to absorb and neutralize that electric zap. It's like catching lightning in a jar, but instead, Yoda just absorbs it into his green, wrinkly skin.
