The current i in an electrical conductor varies inversely as the resistance R of the conductor.
----
i = k/R^2
---
Solve for "k" using "The current is 8 amperes when the resistance is 895 ohms."
8 = k/(895)^2
k = 8*(895)^2
-------
Equation:
i = [8*895^2]/R^2
-------
What is the current when the Resistance is 848 ohms?
i = [8*895^2]/848^2
i = 8.9114 amperes
