A small generating station produces 120 kW of effective power that is transmitted by two wires, each having a resistance of 0.045Ω. How much power is saved by transmitting the power at 2.5 kV instead of 120 V?
Ohm's law
Ohm’s law is a prominent concept in physics and electronics. It gives the relation between the current and the voltage. It is used to analyze and construct electrical circuits. Ohm's law states that the voltage across a conductor is directly proportional to the current flowing through it.
Path of Least Resistance
In a series of alternate pathways, the direction of least resistance is the actual or metaphorical route that offers the least resistance to forwarding motion by a given individual or body.
