the larger the cross sectional area, the smaller the resistance
You cannot create a cross sectional area of a rectangle. You can only create cross sectional areas for triangular shapes.
To calculate Cross Sectional Area: Width x Depth
The cross sectional area of a slab can be found by squaring the height of the slab.
reduction ratio= initial cross sectional area/final cross sectional area
Cross-sectional area = pi*radius2
Other things being equal, more cross-sectional area will cause less resistance.
The resistance is based on the cross sectional area. It is conceivable that you could bend a wire in such a way as to affect the cross sectional area, but unlikely.
Resistance is inversely-proportional to the cross-sectional area of a conductor. For example, doubling its cross-sectional area will halve its resistance, while halving its cross-sectional area will double its resistance.Since the cross-sectional area of a circular-section conductor is proportional to the square of its radius, doubling that radius will reduce its resistance by one quarter, while halving its radius will quadruple its resistance.
Resistance is inversely proportional to cross-sectional area. so ,if the thickness of the wire increases, the area of cross-section increases and this results in decrease of the resistance. The resistance R = l p / A where R is the resistance, l is the length of the wire, p(rho) is the electrical resistivity of the material and A is the area of cross section. So R the resistance is inversely proportional to A the area of cross-section. If R increases
The answer depends on whether the cross sectional radius/diameter are doubles or the cross sectional area is doubled.
The answer depends on whether the cross sectional radius/diameter are doubles or the cross sectional area is doubled.
The factors are: length, cross-sectional area and nature of substance.
Because it would affect the Cross sectional area of the conductor therefore altering the resistance.
the resistance can never increase or decrease....... (you can't open the resistor and take out the something and make the resistance increase or decrease)AnswerSince resistance is directly proportional to the length of a conductor, increasing the length of a wire will increase its resistance. For example, if you double its length, you will double its resistance.
Since resistance is inversely-proportional to cross sectional area, the lower the cross-sectional area, the higher the resistance. So ALL types of wire exhibit this behaviour!
When it is on the cross-sectional area it is inversely proportional to the wire,otherwise it is directly proportional to the wire.
1.Resistance is dependent on the material.Like wood is insulator(ALMOST infinite resistance). 2.Resistance of a wire having more cross sectional area is less and less cross sectional area is more(i.e. it is inversely propotional to the cross sectional area.) 3.It is more for more length and less for less length. 4. Resistance varies with temprature.For metals like platinum it increses with temprature.
