Question 511563
The current I in an electrical conductor varies inversely as the resistance R of the conductor. 
---
I = k/R
----
Solve for "k" using "current is 9 amperes when the resistance is 980 ohms".
---
9 = k/980
k = 8820
----
Equation:
I = 8820/R
-------

What is the current when the resistance is 580 ohms?
I = 8820/580
I = 15.21 amps.
