(9)(980) = (I)(580)

(980 \Omega) = (x A)(580 \Omega))
, solve for x.
Or if you know Ohm's law, you can solve it but it reduces down to the previous equation.

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.
