Question 842314: 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 resistance is 240 ohms,find current when the resistance is 150 ohms.

Hi!
This would fall under algebraic ratios:
Okay so your current ratio is 50:240 = 5:24
Now if you decrease your R (resistance) to 150ohms, you're effectively increasing your current A.
So 240/150 = 1.6
Now multiply 50 x 1.6 = 80 Amperes
To crosscheck with this, you can also use the V=IR formula (Physics)
V = 240. 50 = 12000V
12000= 150 . A
Therefore 12000/150 = 80Amperes
Hope this helped! :)
