The current in an electrical conductor varies inversely as the resistance of the conductor. If the current is 44 ampere when the resistance is 880 ohms, what is the current when the resistance is 400 ohms?
-------------------
c = k/r
------
Solve for "k":
44 = k/880
----
k = 44*880
k = 38720
-----
c = 38780/r
what is the current when the resistance is 400 ohms?
current = 38780/400 = 96.8 am

i=e/r
e=ir
e=44*880
e=35200v
---------------
i=e/r
i=35200/400
i=88a
