What is an injection substation?
An injection substation is a substation where a higher voltage is stepped down to a lower voltage,especially for transmission in a densely populated area.The transformer involved is often in the MVA range,so that the output can serve a wide area,or large consumers. In Nigeria,the common injection stations are: 15MVA or 7.5MVA 33/11kv injection substations.

What are step-up and step-down transformers?
A Step Up Transformer is one whose secondary voltage is greater than its primary voltage. This kind of transformer "steps up" the voltage applied to it.The Step Up transformer is designed to increase the voltage from the primary winding to the secondary winding.A Step-Down transformer is one whose secondary voltage is less than its primary voltage. The step down transformer is designed to reduce the voltage from the primary winding to the secondary winding. This kind of transformer "steps down" the voltage applied to it.The basic equation for stepping up or stepping down the voltageNp/Ns is known as the turns ratio.The induced voltage in the secondary winding (Vs) is in proportion to the primary voltage (Vp) and is given by the ratio of the number of turns in the secondary (Ns) to the number of turns in the primary (Np).I to answer basic transformer questions.
How is force multiplied by a hydraulic system?
input pressure X area = output pressure X area
Which area of technology might be associated with solar panels?
Energy or energy transfer is associated with solar panels.
What happens to voltage when wire length increase?
When the length of the wire increases voltage drop across the wire will occur.There are two factors that can result in voltage drop. One diameter of the wire, two length of the wire.Voltage drop increases with increase in length of wire, whereas voltage drop decreases with increase in diameter (cross section area) of the wire.G.RAOAnswerIf you are asking what happens to the voltage across a length of wire when its length increases, the answer is nothinghappens! The voltage applied to the wire is determined by the supply, not by the load (i.e. the wire).
How area of solar panel affect voltage?
It is not based on the area really... basically for each photo voltaic cell they have a certain voltage, if you connect them in series such as -------0-------0----------0---------0--- then it will increase the voltage 4fold but not the amplitude if they are connected in parallel then amplitude will increase but not voltage. Usually panels have a mix of both to get a good voltage and amplitude |--------0-----| |--------0-----| |-------0------| |------0-------| |------0-------|
Does the output voltage of a solar cell depend upon the area of its surface exposed to the light?
yes, along with many other factors. Solar cells use the ultraviolet band of energy from a light source above the other bands. This is why incandescent lights do not provide as much power as a florescent lamp or why solar panels use quartz instead of glass covers.
How the power output of solar panels fitted to a house can change?
The output of solar panels depends on the surface area that is exposed to light. For a given light intensity, the larger the area, the greater the power output.
How the power output of solarpanels fitted to a house can change?
Well the output of solar panels depends on the surface area that is exposed to light. For a given light intensity, the larger the area, the greater the power output.
How does sunlight intensity and the surface area of a solar cell affect it's electrical power output?
The larger the area surface of the solar cell the more energy output is made, because of it has more area so that it can intake more sunlight so therefore it can give more of its energy of more quickly.Most obviously the more sunlight intensity on the solar cell the more energy it given off because sunlight = energyso the more sunlight that has been inputed into the solar cell the more output energy will be given off.
How does the output voltage of a solar cell depend on thearea of the solar cell exposed to the light?
because the out put voltage of a solar cell is directly proportional to the area of the solar cell exposed to sun light. Testing your solar cell with the application of shading will cause a loss of power and lower voltage and current at the peak power point, However, if you are measuring open circuit voltage only, and this is only one cell, not a collection of solar cells making up one solar panel, the open circuit voltage will stay almost the same until full shade is applied. I would need more information on the solar cells such as are there many in one panel that you are testing or just one solar cell. Is it an array you are testing or just one panel? I will assume it is one panel since you said "solar cells". This means the first statement I made holds in that the open circuit voltage will change very little with the application of shade. A better test is to measure the short circuit current flow. Short the output leads together and measure the maximum current yo can get in full sun light. Now apply your shading and continue measuring the current. Make up a table Shade---------------------Current Measured 0%--------------------------2 amps 10%------------------------1.8 amps . . . 80%-----------------------0.4 amps Now repeat the measurements only this time open circuit the solar cells, no load of any kind, just the voltmeter. Shade-----------------------Volts 0%---------------------------35 volts 10%-------------------------35 volts 50%------------------ To complete the testing use a variable resistor and a watt meter. Make a table recording the the shading and maximum power you could develop and the voltage across the resistor. For instance, in full sun light, adjust the resistance until you get the peak or maximum power reading on your watt meter.
How does the surface area of a mitochondrion or chloroplast affects its energy output?
increased surface area, increases output

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
Does the sun's energy output remain constant overtime?
Solar output is nearly, but not quite, constant. Variations in total solar irradiance were too small to detect with technology available before the satellite era. As the Earth rotates, the energy from the sun is distributed across the entire surface area. At any given moment, the amount of solar radiation received at a location on the Earth's surface depends on the state of the atmosphere, the location's latitude, and the time of day.
What controls how much solar energy is received at a given location?
How much given solar energy is received in a given location is that you have enough sunlight to create solar energy because solar means light waves from the sun. So if there is a lot of sunlight in your community/area you will get a lot/or a medium amount of solar energy, but if you don't have a lot of sunlight in your community/area then you won't get a lot of solar energy. Angle of deflection and shade trees, as well as cloud cover have a direct effect on the amount of convertible lightwaves available for conversion to electricity.
How many watt does a Solar cell output?
Solar cells are available in sizes (power outputs) ranging from a few milliwatts to kilowatts and more. It's all about size (the area and number of the cells) and a few other factors. Arrays of solar cells that some call solar panels will deliver energy in a range dependent on the wiring and size of the array, the attitude of the mount, and the geographic location and weather in the area in which it is erected. Just think it through and it will become apparent. Probably the most critical factor as regards the power output of the unit or assembly is termed the maximum power point. Power out is determined by current times volts. At some "happy medium" between maximum current and maximum voltage (neither of which is the "best" point of operation) is that magic combination of volts and amps that result in the solar cell delivering maximum power ( with other factors optimized, of course). It's the electronics support circuitry that controls the point of best operation. Start reading and come up to speed on this amazing principal of power generation. Begin with the link provided. One thing to note is that efficiency of a panel is also taken into consideration are you using a Serengeti with a 13% solar cell efficiency or SPR 225 with an 18%. The efficiency effects the amount a solar cell will output.
