Question 1197102: The current (I) in an electric circuit is inversely proportional to the resistance (R). If the resistance is 10 ohms when the current is 0.2 ampere, find the resistance when the current is 1.2 amperes. (Round your answer to two decimal places.)

R =__________ohms

Hi

The current (I) in an electric circuit is inversely proportional to the resistance (R)
I = k/R  0r k = I*R
I%5B1%5D%2AR%5B1%5D+=+I%5B2%5D%2AR%5B2%5D
resistance is 10 ohms when the current is 0.2 ampere
find the resistance when the current is 1.2 amperes
.2%2A10+=+1.2%2AR%5B2%5D
%28.2%2A10%29%2F1.2+=+R%5B2%5D = 1 2/3 ohms
Wish You the Best in your Studies.
