Is it true that the bigger sized cable offers less resistance to current flow?
yes
Which Materials which offers low resistance to flow of current is a good conductor?
All of them. That's the definition of "conductor".
What terms is used to describe a wire which offers obstruction to the path of electric current?
A resistance or resistor.
Why shunt resistance must be small in ammeter?
An ammeter has to measure to current flowing through the circuit. Resistance offers an obstruction to the current flow. So, if the resistance of an ammeter is large , the current measured by the ammeter will be quite less as compared to the actual amount of current flowing through the circuit which is undesirable. If ammeter has zero resistance , then it will give the exact value of current. But this is not practically possible because every material has some value of internal resistance which we can't control. For this reason , ammeter must have small resistance
What offers resistance to the circuit and limits the amount of current that can flow?
The internal components of a device that has been manufactured by a company adds up to the internal resistance of the device. Some devices are higher in resistance, some are lower. The results that you can see is on the device's nameplate and is represented by the wattage that the device draws.To answer the second part of the question, the answer is Ohm's law. The current of a circuit is directly proportional to the applied voltage and inversely proportional to the resistance of the circuit. In other words if the voltage remains the same, the higher the resistance the lower the current draw. A short circuit is no resistance, very high current. This is why over current protection is needed in most electrical circuits.
What does streamlinne mean?
There is no such English words as "streamlinne". However "streamline" means to shape in such a way that the product offers the least resistance to a current, as of air or water.
Why is a copper wire in a closed circuit does not get heated but a nichrome does?
this is because copper wire offers no resistance and thus electric current passes through them without producing heat energy whereas in nichrome offers a large resistance and thus the mechanical energy of the drifting electrons changes to heat energy rapidly .
How does an energy circit flow?
In an incandescent bulb, the current flows through a thin tungsten wire or a metallic filament that offers high resistance to current flow. When the electrons bump into the atoms, the friction, or loss of kinetic energy, produces heat
Which Property of material offers resistance to scratching is?
Hardness
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 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 forms anti bodies and offers resistance to diseases?
The immune system.
