A washing machine in a home has a power of 4,500 watts and runs on a 220-volt household circuit. (a) What is the current through the washing machine? (b) What is the resistance of the washing machine? (c) How many kilowatt-hours of electricity are used by the washing machine if it is used for 5 hours in one week?
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.
