An extension cord made of two wires of diameter 0.129 cm (no. 16 copper wire) and of length 2.7meters is connected to an electric heater that draws 18.0A on a 120-V line. How much power is dissipated in the cord?
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.
