What are the steps taken to decrease the resistance?

Answer 1

yes more info plz.

Answer 2

Resistance of a conductor R = S L/A. Where S is specific resistance which depends on the nature of the material, L is length and A is area of cross section. Choosing a wire of low specific resistance and a long thick wire gives low resistance.
Another method is to the given conductor if another conductor of low resitance is connected in parallel, the resistance of the combination will be less than the minimum resistance used in the combination.

Answer 3

1. It depends upon the material.The prpoerty is called the resistivity, if the resistivity is low resistance is low. Depending upon the resistivity the materials are classified to insulator and conductor . now research is going on superconductor, which has zero resistance .
2. Resitance is directly proportional to length and inversely proportional to the area of cross section , so decreasing length and increasing area we can decrease the resistance.
3.by combining the resistances in pararallel, the net resistance decreases.

Answer 4

Evolution of bacteria towards resistance to antimicrobial drugs, including multidrug resistance, is unavoidable because it represents a particular aspect of the general evolution of bacteria that is unstoppable. Therefore, the only means of dealing with this situation is to delay the emergence and subsequent dissemination of resistant bacteria or resistance genes. Resistance to antimicrobial drugs in bacteria can result from mutations in housekeeping structural or regulatory genes. Alternatively, resistance can result from the horizontal acquisition of foreign genetic information. The 2 phenomena are not mutually exclusive and can be associated in the emergence and more efficient spread of resistance. This review discusses the predictable future of the relationship between antimicrobial drugs and bacteria.

Answer 5

from the releation it can be stated that resistance can be decreased
by three ways,
1. by shortening the length,
2. by increasing the area,
this is in general, but for specific cases other techniques are there

Answer 6

B4 knowing how to decrease resistance u should know the factors on which it depends.
it depends on length of conductor, area of conductor, and on resistivity which further depends on material.
ways of decreasing resistance are
(1)take wire or conductor of less length
(2)take wire with low area of crossection otherwise streach the wire u have.
(3)take wire with low resistivity
(4)u can also use a parell combination.

Answer 7

While the terms voltage, current and resistance are fairly intuitive terms, beginning students of electrical engineering might find the analog terms for water flow helpful. Water pressure, typically measured in pounds per square inch, is the analog of voltage because establishing a water pressure difference between two points along a (horizontal) pipe causes water to flow. Water flow rate, as in gallons of water per minute, is the analog of current, as in coulombs per second. Finally, flow restrictors such as apertures placed in pipes between points where the water pressure is measured are the analog of resistors. We say that the rate of water flow through an aperture restrictor is proportional to the difference in water pressure across the restrictor. Similarly, the rate of flow of electrical charge, i.e. the electrical current, passing through an electrical resistor is proportional to the difference in voltage measured across the resistor.

Electrical resistance=(length/area)*specific electrical resistance.
From above it is clear that either you reduce the length or increase the cross sectional area.
Resistivity is a measure of the material's ability to oppose the flow of electric current.

Answer 8

you can decrease the resistance by using parallel connections rather than series moreover as resistance is directly proportional to length and inversely to area ,so,u can decrease it by area or using thick wiresof small length

Answer 9

current is directly propotional to resistance,so the current can be decreased then the resistance will also be decreased
