A shock that leads to death is known as electrocution. The chances of a shock resulting in electrocution vary between different games and can depend on other circumstances within the game.
In The Sims, all electric shocks result in death by electrocution. Sims have a high chance of electrocution while repairing an electrical object with low mechanical skill. This chance decreases, but never drops to zero, as mechanical skill increases. Sims will always get electrocuted when repairing an electrical object while they are standing on a puddle, regardless of skill.
The Sims Bustin' Out (on console)Edit
In The Sims Bustin' Out on console, one item in electronics is a bug zapper. An adult Sim has the option to "Touch" a bug zapper, and can be electrocuted, but will not die. It does increase their energy motive and decreases other motives.
The Sims 2Edit
In The Sims 2, electric shock causes a large drop in all of a Sim's needs. If this puts three or more of the Sim's needs at extremely low levels, they will be electrocuted and die. Sims who survive a shock get the "Shocked" memory. Their hair will be burnt after being shocked, and their faces will be smudged. This can be fixed by bathing or showering or using the "Change Appearance" option on a mirror. With the addition of influence in the University expansion pack, it is possible for non-controllable Sims to be shocked when influenced to do repairs. Seasons adds the further risk of being shocked by lightning, and Open for Business expansion adds the risk of a Servo running amok and shocking anyone who is on the lot.
In The Sims 2 for console, Sims with low mechanical skill can also get shocked while operating a DJ booth. This will happen when the machine effects are deployed (laser, fog, and fireworks). This shock will result in electrocution, and will kill the Sim immediately.
The Sims 3Edit
In The Sims 3, Sims get the singed moodlet after getting shocked for the first time. The lightning will cause the Sim to have burned clothing and messed up hair. If the Sim gets shocked again with the singed moodlet, the Sim will be electrocuted, unless they are repairing a computer. If the Sim has the unlucky trait, they will immediately be electrocuted regardless of being singed or not. Electrocuted ghosts look yellow and have electric currents running through their body. Sims usually are shocked if they try to repair an object with a low handiness skill, or if an upgrade fails on an object. Sims have a higher chance of getting shocked if they are also standing in a puddle of water while attempting to repair an electrical object. In Supernatural, Sims may be shocked if they eat a jelly bean. In University Life, Sim may be shocked when they are doing brain enhancement.
