Problema Solution
If the voltage V in an electric circuit is held constant, the current I is inversely proportional to the resistance R. If the current is 50 amperes when the resistance is 285 ohms, find the current when the resistance is 150 ohms
Answer provided by our tutors
I = V/R
50 = V/285
=> V = 285*50
Thus, I = 285*50/R
When R=150, I = 285*50/(150) = 285/3 = 95
Answer: 95 amperes
