The current I in an electrical conductor varies inversely as the resistance R of the conductor. The current is amperes when the resistance is ohms. What is the current when the resistance is ohms?

Step-by-step explanation:

From above:

let assume that;

The current is ampere when resistance is 240 ohms.

Now, to find the current when R = 540 ohms.

SO; if

where k = constant

Thus; the constant = 120

So; when R = 540 ohms

then the current will be:
