Question 43997: Inverse variations
The current I in an electrical conductor varies univesely as the resistance R of the conductor. If the currant is 1/2 ampere when the resistance is 230 omhs, what is the current when the resistance is 540 omhs?
please help set this up

OK, so the current varies inversely with the resistance. We can write:
where x is a fixed constant value.
Rearranging:
When I=230, R=1/2, and this tells us that x=230/2=115
so when R=540,
Giving the solution I=62100 amps
I hope this helps.
I would be extremely grateful if you would send me your feedback on my help to adam.chapman@student.manchester.ac.uk.
