(a) An electric train operates on 900 V. What is its power consumption when the current flowing through the train's motor is 1,960 A? (in W) (b) An electric clothes dryer is rated at 3,200 W. How much energy does it use in 50 min? (in kWh)
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.
