The most efficient way to channel electricity power from the power station.
Question:

Look at the map. See  the power station “orot rabin”.

See the diagrams of the power station.

The electrical current flows from the power station to the consumers through electric cables.

The electrical current leaves the power plant with a voltage as high as 750,000 volts

At the substation transformer the voltage is lowered to about 2000 - 13000 volts

At the farthest transformer (near the customer)  the voltage is lowered again to  120 or 240 volts

Watch the simulation of Ohms-law and note any changes in the current.  Remember what you learned about Ohms-law.

Watch the simulation of circuit-kit-DC and note any changes in the power change.  Remember what you learned about the power of the electricity circuit.

We learned that the power of an electrical circuit depends on the voltage and the current. In fact the power formula is: P=VI=RI2

What is the most  efficient way to channel the electricity power from the power station?

 Raise the voltage as high as possible, so as to minimize the current (per unit of power), in order to reduce power loss.
 The electricity power should be channeled from the power station should go through a lot off electrical insulation, to reduce power loss.
 Minimize the distance from the power station to the customer, so we have to replace the cotstomer. The shorter the distance, the bigger the loss.
 The electricity current, which is channeled from the power station, does not match the Ohm's Law. So any change in the cable will not affect loss.
