A 1520-W hair dryer plugs into a 120-V outlet. What is the current through the hair dryer when it is turned on? At a cost of $0.100 per kW·h, how much does it cost to run the hair dryer for 5.00 min? Answer in cents
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.
