It could, because Electric attacks do neutral damage against Bug-type Pokemon. In this case, it depends on the offensive and defensive stats of the two Pokemon, along with other factors such as status effects and attacks and critical hits.
A Water Pokemon's weaknesses are Electric and Grass. Basically any type of Pokemon can beat a water Pokemon if it's strong enough, but Electric and Grass attacks do 2X damage against Water types. Water types also only take half damage from Fire, Ice, Steel, and Water attacks, so those wouldn't be the best ones to use. Water attacks do half damage to Dragon, Grass, and Water Pokemon. Its strengths are against Fire, Ground, and Rock.
Ground type pokemon have attacks such as ground type attacks that are super effective against electric type pokemon such as pichu. good examples include Dugtrio, Groudon, and Donphan
No. Electric attacks make regular damage to Ice.
Electric, Ice, and Rock Type attacks are super-effective (2X damage) against Flying Types, so those are the best ones to use. Ground attacks do ZERO damage against flying types, so that would be pointless. Grass, Bug, and Fighting attacks only do half damage against flying types, so those aren't ones you want to try. Flying attacks are strong against Bug, Fighting, and Grass, and ineffective against Electric, Rock, and Steel. So, best case scenario, you get an Electric, Ice, or Rock Pokemon in there with a signature strong attack of the same type.
Steel-Type attacks deal 2X to Ice- and Rock-Type Pokemon, and 0.5X damage to Fire-, Water-, Electric- and other Steel-Type Pokemon.
No, they do neutral damage.
Grass. The grass type deals standard damage to the electric type, but electric moves are only 1/2 as effective on the grass type. Both fire and normal types could probably stand up against electric attacks as well. Don't use water unless it is a combination of water and ground types; electric attacks don't cause any damage to ground types. In fact, ground is actually the best choice when battling an electric type pokemon.
Lapras is a Water / Ice type Pokemon. Therefore Electric, Grass, Rock, and Fighting attacks are super effective (they do 2X damage). Lapras is resistant to Water and Ice attacks (they do half damage), so those aren't good ones to try.
Eelektross has no type weaknesses. Though Electric, it is immune to Ground-type attacks because of its ability Levitate. However, if Eelektross' ability is negated or changed, then Ground-type attacks will do twice as much damage.
Ground type attacks are strong against Electric type Pokemon (super effective--2X damage), and everything except Flying, Steel, and Electric works normally against them (effective--1X damage). Flying, Steel, and Electric moves are not very effective against electric (half damage). Also, if your Pokemon is the same type as the type of the attack it is using, the attack power increases by 50% (Same-Type Attack Bonus). So, the absolute best thing you could do against an Electric Pokemon is have a Ground-type Pokemon attack with a strong Ground-type move, such as Earthquake, Dig, or Drill Run.
Nothing else does x2 or more damage against purely electric pokemon, but electric moves only do half damage to dragon, electric, and grass pokemon.
