For a line of given cross section and material, the power capacity will depend on the current carried, since resistance heating is proportional to (current)2 . For a given power, current is inversely proportional to voltage. Thus raising the voltage from 69 to 390 kv would reduce the current by a factor 69/390 = 0.177 , for the same power transmission, and reduce the heating losses by 0.1772 = 0.031. So you can see why high voltage for long distance lines is essential.
Obviously the limiting current on a power line has to be set by economic and practical considerations, but if this is predetermined and set, the limiting power will be that which produces that limiting current, and power = voltage x current. The actual limiting curent will depend on the line cross section, material, and length. The power that a line of a certain voltage can carry is calculated by using the following formula: (2.55×(KV)2 /1000) MW.

There isn't a formula for finding joules. It is a way for finding a force or giving an example.

Look at the formula for gravity. It depends on the masses (as well as on the distance). In this case, the mass of planet earth is quite huge.
The formula is Resistance= Voltage/ Amps(current) In your example: R=50/2.5, so the answer is 20 ohms.
The transmission capacity is based on a formula describing the power between a transmitter and a receiver. The ratio of these two numbers and the formula describes the capacity of the channel.

The capacity of a container is the volume of its inside. There may or may not be a formula for that - it depends on the complexity of the shape.The concept of capacity also appears in many other contexts, for example,In law: capacity refers to the ability to make "sensible" decisions.In economics: the maximum amount of output possible, usually given existing capital resources.

The formula for water capacity in storage tank is following,Dia of tank X dia of tank X .785 X Height of tank X 6.2 X 4.54 = LiterFor Example,Dia of tank is 10ft.Height of tank 15ft.So,10 X 10 X .785 X 15 X 6.2 X 4.54 = 33144 Lit (its the tank capacity)
First, you must know the length, the width and the height. Then you multiply all of them and you get the capacity.
