Why is the grounding conductor flat?
When stranded conductor is being used for earthing, It offers some reactance in addition to the resistance of the conductor. Since any kind of surge is of sudden in nature, and reactance opposes the change in flow of current (Property of Inductor), It might disturb the discharge rate of the surge. Hence the conductor is flat inorder to provide only the resistance
What would result from increasing the resistance in a series circuit with one resistance (load)?
Resistance refers to the property of a substance that impedes the flow of electric current. Some substances resist current flow more than others. If a substance offers very high resistance to current flow it is called an insulator. If its resistance to current flow is very low, it is called a conductor. Resistivity refers to the ability of substances to resist current flow. Good conductors have low resistivity and insulators have high resistivity.Factors upon which resistance dependsThe resistance R of a conductori. is directly proportional to its lengthii. is inversely proportional to its area of X-sectioniii. nature of the materialiv. changes with temperature.From the first three points, R = p l/ A where p = rho and is a constant of proportionalityOr, if the resistance is increased,current flow will decrease(I = V/R).Looking at the first three factors ,area of X-section will be decreasing.
What weight resistance does the total gym 3000 offer?
The total gym 3000 offers a variety of weight resistance training. It has a 300lb weight capacity, very comfortable system, pulley and cable systems and other upgraded features. It also has a range of 60 different excercises.
How does the earth wire protect you from a short circuit?
An earth wire only " works " under fault conditions in an electrical circuit . The earth or circuit protective conductor protects any conductive part of the system which under normal conditions should not be live , for example the metal casing of a washing machine . The earth , during a short circuit , will complete the circuit and the system will fuse/trip/disconnect if protected suitably .

What is the advantage of using a stranded copper conductor over a solid copper conductor?
It would of course depend on the specific application. Current tends to travel on the surface of a conductor and a stranded conductor has more surface area and thus offers less resistance to the current. Stranded wire also bends a bit easier than the corresponding size solid wire.
Why is aluminum a better conducter of electricity than sodium?
'Voltage' isn't 'conducted'. Voltage can be thought of as 'electrical pressure' which, when applied across opposite ends of a conductor will cause a CURRENT to flow along that conductor. So your question should really be asking, why aluminium conducts a greater CURRENT than iron. The answer is simple. Aluminium is a better 'conductor' than iron. In other words iron resists the flow of current more than aluminium does. Or to express this in another way, iron offers a greater RESISTANCE to the flow of current. Resistance is a natural property of a conductor, with some conductors have more, or less, resistance than other conductors. The best conductor, i.e. the one with the least resistance, is silver -closely followed by copper. Iron is a relatively poor conductor in comparison with silver, copper, or aluminium.
When electrons flow with Little resistance through a conductor it is called a?
A conductor is an electrical path which offers comparatively little resistance. Some examples of good conductors are silver, copper, aluminum, zinc, brass, platinum, iron, nickel, tin, and lead.
What is an electric conductor and insulator?
An electrical insulator is a material that resists electric current, and will not allow it to flow easily. Examples include glass and most ceramics. An electrical conductor is a material that offers very little resistance to electric current, allowing it to flow freely and easily. Most metals make excellent electrical conductors.
What changes electrical energy into heat?
when electrons flow through a conductor then the material of the conductor offers resistance to excite the electrons in the conductor to release heat energy.
Is it true that the bigger sized cable offers less resistance to current flow?
yes
What type of resistance - high or low - do conductors and insulators have?
A component of a given size that offers low resistance is called a good conductor.A conductor having some appreciable resistance is called a resistor.A component of identical size that offers a higherresistance is called a poor conductor.An insulator of the same size offers even higherresistance.
How fan regulator works?
A fan regulator is a crucial component that serves to increase or decrease the speed of your fan according to your needs. To understand how a regulator works, you must know something about resistances. Any electrical conductor allows current to pass through it. The conductor however, offers a certain amount of resistance to the passage of current. The resistance depends upon the material of the conductor. The regulator has spools of wire with different amounts of resistances. When you set the knob at a particular position, you include a certain resistance in series with the fan. A series connection implies the resistance is in line with the fan. This reduces the voltage drop across the fan and its speed to your desired level. The greater the resistance, higher is the voltage drop across it and that lowers the speed of the fan.

Why some materials offer different resistance?
SOunds like a homework question. But ok I'll answer. Ceramics is one major material used for resistance. BUT if you want to impress your teacher, you can say that ALL materials (even gold) offers some level or resistance, just very little)
What terms is used to describe a wire which offers obstruction to the path of electric current?
A resistance or resistor.
