In order to count to 5, you need 3 flip flops and some logic to reset after the count of 5 is reached, i.e. to keep from going on to 7.Or the count of 4, if you are starting at 0.
Engineers request that 5 meg ohm is the bottom limit. I use 1 meg as a bottom limit when megging conductors before they are energized. I have run motors as low as .5 meg, when the moisture is driven out by the heat of the motors operation the motors usually climbs up to about 2 meg ohms.
Basically, the electron shells in an insulator are complete. That means they are not prone to donating any of their electrons and also cannot accept any further electrons from the material external to the insulator. As such insulators aren't waystations for electrons looking to move (conduct). There's a bit more to it. Consider, for example, Carbon (column IV) which, at least in diamond form, is an outstanding insulator. It's the CRYSTAL, the diamond, that has the aforementioned "shell completeness". Pure Silicon (also column IV) has the same characteristic behavior. You can change these pure crystals from insulators to semi-conductors and then conductors by adding increasing amounts of impurities to the crystal, such as atoms from Columns III and V. To carry this further, while Sodium (Na) is a conductor, PURE Sodium Chloride (NaCl, common salt) is an excellent insulator. (Again, with impurities added, it becomes a poorer insulator and better conductor.) It's the crystal's electron shell structure that's complete. HOWEVER, common salt, NaCl, is very soluble in water. So, while pure water is a poor conductor, a common salt solution becomes highly conductive. When salt crystals are dissolved copious amounts of imbalanced ions are ready to donate or accept electrons. More simply: The outer shell of a conductive atom has 3 or less electrons in its outer shell, semi-conductive atom has 4, and an insulating atom has 5 or more.
=== === == == The process of replacing the equipment that comprises your service is simple and straightforward.1. Get a permit.2. A trained person cuts the service conductors so that they don't interfere with the utility company lines [so they can splice back in]!3. Remove the circuit conductors from the old panel.4. Demolish the old service.5. Install the new service.6. Reconnect the circuit conductors.7. Tie the new service cable back into the utility lines.8. Call for inspection.As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.Before you do any work yourself,on electrical circuits, equipment or appliances,always use a test meter to ensure the circuit is, in fact, de-energized.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.
Insulators: Rubber, glass, plastic, ceramic, and wood. Conductors: Copper, aluminum, gold, silver, and iron.
Enorder for materials to conduct electricity they need to have free electrons which carry the current. Materials which can do this include metals, water, Ionic salts when in there molten or aqueous states. Wood, plastic, gases and covalent compounds do not have free electrons and therefore do do conduct.
Copper, silver, gold, aluminum, and steel are materials that allow electricity to flow through them, as they are good conductors due to their high electrical conductivity.

Conductors- which conduct electricity... Allow heat and electricity to pass through them.... Eg: metals like gold, silver, copper,etc. Insulators- which do not allow eletricity and eat to pass through them. Eg: glass and rubber - do not conduct electricity.
Conductors are materials that will allow electricity to flow through them. Materials that contain 1, 2, or 3 valence electrons are good conductors. Some examples of good conductors are gold, silver, aluminum, and copper. Insulators are materials, or combinations of materials, with a high number of valence electrons (5, 6, 7, and 8). Examples of good insulators are porcelain, glass, air, and rubber.

The five main types of materials are metals, polymers, ceramics, composites, and semiconductors. Metals are typically good conductors of heat and electricity, while polymers are lightweight and can be molded into various shapes. Ceramics are known for their hardness and high melting points, and composites are materials made from a combination of different substances. Semiconductors have properties between conductors and insulators and are crucial for electronics.
Good conductors of electricity include metals such as copper, silver, and gold, as well as materials like graphite. These substances have a high density of free electrons that can easily carry electric current. On the other hand, insulators like rubber, glass, and plastic are poor conductors of electricity because they have very few free electrons available for conduction. Semiconductor materials like silicon and germanium have intermediate conductivity levels, making them useful for electronic devices.
There are a great many conductors in the world. These conductors can include musical conductors and electrical conductors for example.
