A small city requires about 15 MW of power. Suppose thatinstead of using high-voltage lines to supply the power, thepower is delivered at 120 V. Assuming a two-wire line of0.50-cm-diameter copper wire, estimate the cost of theenergy lost to heat per hour per meter. Assume the cost ofelectricity is about 12 cents per kWh
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.
