Because they don't feel like it.

In order to conduct an electric current a substance must contain a what?
It should contain some IONS, or charged particles.
Why does a pineapple conduct electricity?
Biological materials, such as this one, will usually conduct electricity due to ions in the liquid. Since an ion has an electrical charge, and is relatively free to move around, it can conduct an electrical current.
Can electric current pass through alcohol Explain?
Yes, alcohol is a liquid and has delocalised electrons which can carry the electrical current. Edited: Seriously? Unless there are impurities in the alcohol that are electrolytes, alcohol will NOT conduct an electric current. Alcohols are considered as NON ELECTROLYTES, as they do not ionize and thus will not conduct a current. (Dr.J.)
Can colloids conduct current?
no. not really
Do dry wooden sticks conduct electricity?
Yes and No. No. it's an insulator, and Yes, but very very little.
Why semi conductive materials do not conduct current well and are og little value in their instrinsic state?
why semi conductive materials do not conduct current well & all of little value in their intrinsic state
Why does conduct of electricity require a cord?
Electric current is the movement of electrons. Various materials can conduct current, but the best materials are metals, because they have plenty of electrons which can move freely. Electric appliances, therefore, are provided with cords which contain metallic strands (usually copper) which carry the current.
What is the effect of temperature on an intrinsic semiconductor?
An intrinsic semiconductor is basically a pure semiconductor, though some might argue that a small amount of doping can still yield an intrinsic semiconductor. In the crystal structure of this material, there are very few electrons crossing the band gap into the conduction band, and this stuff doesn't want to conduct much current. But as temperature increases, more electron-hole pairs will appear as electrons jump that band gap and take up places in the conduction band. And if you guessed that increasing temperature will permit the intrinsic semiconductor to conduct current flow a bit better, you'd be right. The intrinsic semiconductor has a positive temperature coefficient. More heat, more conduction under the same conditions.
What materials will conduct the flow of electricity?
While electricity doesn't flow, current does. Conductors are materials that allow the electrical currents to flow through them. Metals are the best conduction, such as silver and copper.
Metal conduct current?
Metal conduct electricity and flow of electricity is the current.
What does thermal and electrical conductivity mean?
Thermal and electrical conductivity are physical properties; they represent the ability of materials to conduct heat or electrical current.

Can ammonia conduct electricity?
Ammonia is a gas. Gases do conduct electricity, as all materials do. However, they conduct electricity so poorly that we consider them insulators. "Electricity" requires the movement of electrons. In a gas, these electrons are too dispersed to provided any measurable current.
Do all electrical conductors conduct current equally well?
No, materials have difference conductance - also the temperature of the material affects how well electricity is conducted.

Does iodine conduct electric current?
no,
