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?
