A 55” TV draws 0.500 A of current when connected to 120 v. (a) How many watts of electricity does the TV use? (b) If the TV is used 4.00 hr per day, how does it cost to run the TV for 30 days at a utility rate of 0.120 $/kwhr?
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.
