Volt Transformation
Transformer is a plain static crest consisting of a mesmeric heart where the chief and lesser windings are made. The voltage is candidly proportional to the number of windings or turns. Thus, if a 120 AC will be connected to the left segment containing 100 turns, 240 volts would be on the right face containing 200 turns.
The enter fringe is classified as the Primary while the Output fringe is classified as the Secondary. Under this train, the transformer is said to be 120 /240 volts walk up transformer with 120 crucial and 240 volts inferior.
The same transformer could be used as pace down transformer by reversing the sell and the weight. The 240 volts will be principal and 120 volts the derived. In succinct, transformers are reversible.
Power and Energy
Power and Energy is too frequently interchangeably used. Power is the technical term for the common word work, and Work, is the product of Power and Time expressed in the following equation:
Energy or Work = Power x Time
What is Power? Power is the rate at which energy is used or alternatively, the rate at which work is done. Since energy and power is synonymous, power implies continuity. That is, the use of energy at particular rate over a given span of time. The concept of power involves time at ther rate of which work is done. Thus, multiplying power by time gives energy.
What is Energy? In electrical terms, energy is synonymous with Fuel. It is associated with work. Energy can be expressed in gallons, liters, barrels or tons or oil, coal, kilowatt hours or consumed electricity and cost of operations. In technical terms, Energy is expressed in units of BTU (calories), foot pounds (joules) or kilowatt hour.
Under the English Unit System, the unit of power is expressed in horse power, BTU per hour, watt and kilowatt. Under the Metric System or SI, it is expressed as joules per second, calories per second, watts and kilowatts. In physical terms, power is also the rate at which fuel or energy is used and expressed as liters of fuels per hour, cubic meter of gas per minute or tons of coas per day, etc.
Power in Electric Circuit
The measuring unit of thrilling warrant is the Watt. When multiplied by 1000, the result is called Kilowatt. Thus, 1000 watts is one Kilowatt. Power has numerous forms; the emotional motor produces mechanical capacity that is careful in language of horsepower. A thrilling furnace produces part or thermal control, and light bulb produces the fervor and light that is measured in terms of candle weight. Watt is the sway stretch.
Voltage and Voltage Drop
Comparatively, in a Series Circuit - Current is the same throughout but voltage differs.
In a Parallel Circuit, the Voltage is the same, but the stream differs.
Take letter that is a peer arrangement, all stream masses cumulatively add. For example, appliances and light oodles tied to a twin track have the same voltage imposed, but each shipment draws a different tide according to its wattage rating.
Another one important standard that is worthy to record is; "The sum of the voltage crash around a track is level to the resource voltage."This opinion is important in a cycle path. On a matching route, each point has the same voltage across it, which constitutes a course by itself. The voltage ditched on lead transport recent is:
Voltage release in lead = Carried flow x Resistance of rope
The potential trouncing in the line conductor can be calculated as the product of the voltage and the present. It is equal to the components resistance period the current squared.
P = I x (I x R) ; P = I2 R
Advantages of the 240 volts over the 120 volts current fund
1. Smaller cable is vital which means, minor in outlay.
2. Less dominance cost.
3. Smaller percentage of voltage plummets.
