Water is a hydrogen-bonded molecular solid in which H and O are held together by a polar covalent bond and each water molecule is held together by hydrogen bonding. A ground rod isolated from the building grounding electrode system An effective path for ground-fault current is required for the normal equipment grounding conductor dirty ground of a branch circuit and the isolatedinsulated. Electrical Wiring Residential 20th Edition Edit edition.

Since both these forces are equal and towards each other both the current carrying wire will be repelling each other. The correct answer is Diamond. Which of the following is not a good conductor.

It is a p-block element. Depending upon the types of impurity added the extrinsic semiconductor is classified into N-type and P-Type semiconductors. Can be used to make electric circuits.

Which of the following rooms or spaces is NOT required to have a grounded conductor at the switch location. However the metals are not brittleBrittle is not a property of metals. The ion availability is very important to conduct electricity.

When two conductors carrying equal current both the conductor experiences a force which is perpendicular to the wire and are equal. Thus false information about the conductor is that It is frequently. Solutions for Chapter 5 Problem 31R.

Which of the following is not recognized as an equipment grounding conductor in the NEC. As the body of pots and pans used in the kitchen are made of metals like copper and aluminium they will be good conductors of electricity and therefore will be categorized as not an insulator. Mg is metallic solid and is a conductor in solid as well as in molten state.

The correct answer is Distilled water. Rigid metal conduit RMC f. An isolatedinsulated equipment grounding conductor is not permitted to be connected to which of the following.

TiO is an ionic solid and is an insulator in solid state but is a conductor in molten state and in aqueous solutions. On this page you will be able to find the answers for. Is a hydrogen bonded molecular solid and is an insulator.

Bromine is a very poor conductor of electricity. Distilled water is a pure form of water that does not contain ions. Example - Copper Aluminium.

Good conductors are those materials which allow electricity to pass through them easily. Which of the following is a good conductor of heat. Silicon is not a conductor it is a semi conductor it only conducts if temperature increases and if it is dopedotherwise it doesnt conduct.

If the inner and outer surface temperatures of the wall are 15circ C and 7circ C the effective thermal conductivity of the wall is a 061 Wm cdot K b 083 Wm cdot K c 17 Wmcdot K d 22 Wm. Bad conductors are those materials which do not allow electricity to pass through them easily. The atomic number of Bromine is 35.

Correct Answer - Option 3. This problem has been solved. Which of the following is not recognized as an equipment grounding conductor in the NEC.

Which of the following materials is a good insulator. Copper allows the passage of heat and electricity quickly therefore it is commonly used as a conductor. But the materials like glass and rubber are nonconductors and they do not have the capacity to transfer heat and electricity through them so they can not be made with these materials.

This is a non-conductor of electricity. Diamond is a naturally-occurring solid. The metal structural frame of the building or structure that complies with 25068C2 or is connected to the grounding electrode system by a conductor not smaller than 30 AWG copper or 250 kcmil.
