The resistance to water flow in a rough or partially clogged pipe is similar to a conductor having high electrical resistance, which slows down the flow of electricity through it. In both cases, the resistance impedes the movement of the respective materials (water or electricity) through the pipe or conductor, affecting efficiency and performance.

What affects resistance in a circuit?
Resistance in a circuit is affected by factors such as the material the conductor is made of, the length of the conductor, the cross-sectional area of the conductor, and the temperature of the conductor. Additionally, resistance increases as the number of components (such as resistors or bulbs) in a circuit increases.
Is A superconductor is A conductor having zero resistance?
Yes, a superconductor is a material that can conduct electricity without any resistance at very low temperatures. This means that once a current is applied, it can flow indefinitely without any loss of energy due to resistance.
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.
Why heater coil glow but supply wire not glow?
The heater coil glows because it has high resistance, causing it to generate heat. The supply wire does not glow because it has much lower resistance compared to the coil, which allows it to carry the current without generating significant heat. Additionally, the supply wire is usually made of a material that can withstand the current passing through it without glowing.
What is the resistance of air gap?
The resistance of an air gap primarily depends on its size and shape, with larger and wider gaps typically having higher resistance due to increased spacing between conductors. Factors like temperature, humidity, and presence of contaminants can also affect the resistance of an air gap. In general, air is considered a poor conductor of electricity, so air gaps have higher resistance compared to solid conductors.

What is a conductor electricity?
In a conductor, electric current can flow freely, in an insulator it cannot. Metals such as copper typify conductors, while most non-metallic solids are said to be good insulators, having extremely high resistance to the flow of charge through them.
Do The resistance of a material generally increases as its temperature increases?
The answer to this depends on the material from which the resistance is made. For most materials resistance increases with increasing temperature. This is referred to as having a "positive temperature coefficient". Some materials have a negative temperature coefficient; these do have uses in electronics.
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.
What is the definition of electrical resistance?
Resistance is the opposition to electric current, expressed in ohms.Resistance is directly-proportional to the resistivity of the conducting material and its length, and inversely-proportional to its cross-sectional area.Alternating current tends to flow towards the surface of a conductor due to the 'skin effect', thus reducing the effective cross-sectional area of a conductor. Therefore, resistance to a.c. is somewhat higher, at normal supply frequencies, than to d.c., and significantly higher at very high frequencies.
Do conductors have high or low current?
Low resistance. Think of Ohm's law. Voltage drop is directly proportional to resistance. The higher the resistance, the higher the voltage drop, and the less voltage that is available for the load. Think of conductor resistance as a resistance in series with the load. Also, higher conductor resistance means more power lost, going to heating the conductors. The "line loss" formula is P=I2R. The greater the resistance, the greater the electrical power being converted into thermal power heating the conductors.
How does the resistance of a conductor compare to that of an insulator?
The resistance of a sample of a conducting substance is less than theresistance of a physically identical sample of an insulating substance.AnswerTo give you some idea of the difference between the resistance of insulators and conductors, a sample of mica (an insulator), just 25-mm long, has the same resistance as a copper conductor, having the same cross-sectional area, but measuring a staggering 14 290 000 000 000 000 000 kilometres long! To put this in perspective, the average distance from the Earth to the Sun is a mere 150 000 000 kilometres!

What would happen if you had a clogged arterie in your head?
that's called having a stroke
How do you know an electrical circuit has a short in it?
A short circuit is determined by a low resistance between two conductors or between a conductor and the ground. <<>> The circuit's over current protection usually trips resulting in the circuit having no power.
What happens when you have low resistance?
Having low resistance means that there is an easier flow of electric current through a circuit. This can lead to higher current levels which could potentially damage the components in the circuit or cause overheating. It can also result in a decrease in voltage across the circuit.
