"The current I in electrical conductor varies inversely as the resistance R of the conductor"
__ I*R=k __ k is the constant of proportionality

.2*200=k __ 40=k

I*250=40 __ I=.16

The current I in electrical conductor varies inversely as the resistance R of the conductor. Suppose I is 0.2 amperes when the resistance is
200 ohms. Find the current when the resistance is 250 ohms.
--------------------
I = k/R
Find k:
0.2 = k/200
k = 40
-----------
EQUATION:
I = 40/R
---------------
If R is 250 ohms, find I.
I = 40/250
I = 0.16 amps
