The advantages are that you will be able to get more things for the business. The disadvantages are that they are a lot of costs.
Don't quote me, but... Monopolies, un fair trade, overhead costs and supply and demand.
One disadvantage to using a predetermine overhead absorption rate is the fact that the rate may be too much for any particular product. If this happens, then the price of the product will be too much.
Combined overhead variance = fixed overhead variance + variable overhead varianceFixed Overhead :which remains fixed and donot change upto certain level of productionVariable Overhead: which keep changing with the change in production units.
Using direct labor hours: Overhead rate = Total Overhead Expenses /Direct labor hours Using Machine hours: Overhead rate = Total Overhead Expenses /Machine hours
Overhead transmission lines are less expensive, in most cases, significantly less expensive, than underground cables. Underground transmission cables require insulation, cooling systems, and -the most expensive feature- excavation!
they are made of alluminium
beacuse is good
A bridge with overhead cables to support it.
power cables under ground rather then overhead.
The advantages are that you will be able to get more things for the business. The disadvantages are that they are a lot of costs.
First of all, the overhead lines are cheaper because they are bare, while underground cables are armoured and insulated, hence explaining the higher price. Overhead cables come of course with accessories like poles and insulators (mostly porcelain). For shorter distance, underground cables are preferred as the cost of pole erection does not exist.It's also worth pointing out that the cost of excavating a trench is more expensive than erecting an overhead line, and this cost escalates dramatically with higher voltage systems. For example, a 132-kV double-circuit underground line is between 5 and 8 times the cost of an overhead tower line, whereas an 11-kV single-circuit underground line is up to twice the cost of a wooden-pole overhead line.
Advantages: Pollution can be kept away from cities and large power stations can be built (more efficient Power can be diverted to where it is needed, if there is high demand or a breakdown Surplus power can be used to pump water up into reservoirs to be used to generate hydroelectric power when there is a peak in demand. Disadvantages: Power is wasted heating the cables Overhead power cables are an eyesore Smaller generating projects such as wind turbines and panels of solar cells have difficulty competing with large suppliers
A. you can go under water. D. if they break you die.
Advantage: everything. Disadvantage: cables and less mobility.

By overhead cables, supported on masts, at very high voltage, to reduce the effects of resistance in the wires.
