the current I in an electrical conductor varies inversely as the resistance R of the conductor.
---
I = k/R
---
Solve for "k" using "the current is 1/2 ampere when the resistance is 240 ohms"
(1/2) = k/240
k = 120
---
Equation:
I = 120/R
----
What is the current when the resistance is 540 ohms?
I = 120/540
I = 2/9

I = V/R (using V for voltage, Ohm's law)

volts

Then, the current at 540 ohms resistance will be ampere
