Question 32591: If the voltage V is an electric circuit is held constant, the current I is inversely proportional to the resistance R. If the current is 40 amperes when the resistance is 270 ohms, find the current when the resistance is 150 ohms. Found 2 solutions by Paul, mukhopadhyay:Answer by Paul(988) (Show Source):
You can put this solution on YOUR website! Voltage drop is given by V=I*R
Equation:
40(150)+270x
270x=6000
x=22.22
Hence, the current is 22.22A.
Paul.
You can put this solution on YOUR website! I = k/R
40 = k/270
=> k = 270*40
Thus, I = 270*40/R
When R=150, I = 270*40/(150) = 270*4/15 = 72
Answer: 72 amperes
