Concept explainers

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.

At the same temperature, two wires made of pure copper have different resistances. The same voltage is applied at the ends of each wire. The wires may differ in ( check all that apply) _ a. length _b. cross-sectional area _c. resistivity _d. amount of electric current passing through them Hint 1) The resistivity of a metallic conductor, such as copper, nearly always increases with increasing temperature. Hint 2) For an ohmic conductor, that is, a conductor such as copper that obeys Ohm's law, the resistance R is proportional to the length L and inversely proportional to the cross-sectional area A. That is, R=ρL/A where ρ ie. rho, is the resistivity of the material. Note that ρ is a characteristic of the specific material and may vary with temperature.
