The cost of electricity varies widely throughout the UnitedStates; $0.120/kWh is a typical value. At this unit price, calculatethe cost of (a) leaving a 40.0 - W porch light on for 2 weekswhile you are on vacation, (b) making a piece of dark toast in3.00 min with a 970 - W toaster, and (c) drying a load of clothesin 40.0 min in a 5 200 - W dryer.
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.
