A vacuum cleaner draws power at 1200 Watt. If you clean your once a week, 20 minutes for each session. How much does that cost you in 1 year? Assume that the electricity costs is 5 dollar per unit.
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.
