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.
Question
Transcribed Image Text:1. (a) Find the voltage drop in an extension cord having a 0.065 2 resistance and through which 4 A is
flowing.
V=
V
(b) A cheaper cord utilizes thinner wire and has a resistance of 0.15 2. What is the voltage drop in it
when 4 A flows?
V=
V
(c) Why is the voltage to whatever appliance is being used reduced by this amount? What is the
effect on the appliance?
The voltage supplied to whatever appliance is being used is reduced because the total voltage drop
from the wall to the final output of the appliance is
So, if the voltage drop
across the extension cord is large, the voltage drop across the appliance is significantly
so the power output by the appliance can be significantly
reducing the ability of the appliance to work properly.
