Wires with less cross sectional area are easier to bend and curve around in a circuit. Also, copper costs money, so the more cross-section, then more copper and the cost of building the circuit goes up. Weight savings would be another factor. The maximum expected current load of a section of circuit is calculated, and the size wiring, necessary to handle that current is used.
What else can I help you with?
Why is there less resistnce when you add more wires in a circuit?
Adding more wires in a circuit typically reduces resistance because it increases the overall cross-sectional area available for current flow. According to Ohm's Law, resistance is inversely proportional to the cross-sectional area; more pathways allow more electrons to flow simultaneously. This is similar to adding more lanes to a road, which reduces traffic congestion. However, it's important to note that the quality and configuration of the wires also play a role in the overall resistance.
How do you do a cross sectional area of a rectangle?
You cannot create a cross sectional area of a rectangle. You can only create cross sectional areas for triangular shapes.
How does cross sectional area affect resistance?
the larger the cross sectional area, the smaller the resistance
If wires are made from the same material and are the same length which would have greater resistance?
The wire with smaller diameter (thinner wire) will have greater resistance. This is because resistance is inversely proportional to the cross-sectional area of the wire. Thinner wires have smaller cross-sectional area, leading to greater resistance.
Volume and surface area of prisms a?
Volume = cross sectional area * lengthArea = 2* cross sectional area + perimeter of cross section * length
What is the meaning of Cross sectional area in a river?
Cross Sectional Area = Width x Average Depth
What affects resistance in a circuit?
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.
How do you calculate forging reduction ratio?
reduction ratio= initial cross sectional area/final cross sectional area
How do you work out the cross sectional area of a trapezoidal prism?
cross-sectional area = 0.5*(sum of parallel sides)*height
What is the cross sectional area of a y12 bar?
A Y12 bar typically has a cross-sectional area of 113 square millimeters.
What is the relationship between resistance and cross-sectional area in a conductor?
The relationship between resistance and cross-sectional area in a conductor is inversely proportional. This means that as the cross-sectional area of a conductor increases, the resistance decreases, and vice versa. This relationship is described by the formula: Resistance (resistivity x length) / cross-sectional area.
How do you find cross sectional area of cable when you have the lent current and the voltage drop?
cross sectional area of cable * voltage drop
