Copper wire of diameter 0.259 cm is used to connect a setof appliances at 120 V, which draw 1450 W of power total.(a) What power is wasted in 25.0 m of this wire? (b) Whatis your answer if wire of diameter 0.412 cm is used?
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.
