An electric washing machine draws 2.1 A when connected to a 121 V power line. In Arkansas, the average price of electricity is $0.090 per kilowatt-hour. To the nearest cent, how much does it cost to use the washing machine to wash one load of colors and one load of whites if the washing machine runs for 35 min each time it is used? Remember, round to two decimal places, the nearest cent.

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.
