Concept explainers

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…

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.

Given: power needed to run the TV: 500W What is the cost of running the T.v if we binge watch 5 hours of netflix? Assume the utility rate is 0.10 $/kWhr. Answer: $0.25 Show all work

Power is generated at 24 kV at a generating plant located56 km from a town that requires 55 MW of power at12 kV. Two transmission lines from the plant to the towneach have a resistance of 0.10 Ω/km What should theoutput voltage of the transformer at the generating plant befor an overall transmission efficiency of 98.5%, assuminga perfect transformer?

A step-up transformer increases voltage, or potential energy per unit charge. Howis this possible without violating conservation of energy?
