Physics What is the total cost of using all of the following at 9¢ per kilowatt-hour? (i) A 1200-W toaster for 30 min (ii) Six 50-W bulbs for 4 h (iii) A 400-W washing machine for 45 min (iv) A 4800-W electric clothes dryer for 20 min
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.
