Electric current (i) flowing in a circuit is inversely proportional to resistance (R).The current flow is 2 amps. When the resistance is 3 ohms.
-------------
V = I*R
6 = 2*3
-----------
Find
(1) the resistance when the current flow is 5 and 6 amps
R = 6/I
I = 5 amps
R = 6/5 = 1.2 ohms
--------
R = 6/6 = 1 amp
-----------------
(2) the current flow in a circuit when the resistance is 4 and 6 ohms respectly.
I = 6/4 = 1.5 amps
----
I = 6/6 = 1 amp

Hi,
Electric current (i) flowing in a circuit is inversely proportional to resistance (R).
The current flow is 2 amps. When the resistance is 3 ohms: i+=+k%2FR , 2 = k/3, k = 6
(1) the resistance when the current flow is 5 and 6 amps.respectly.R+=+k%2Fi 6/5 ohms = R, 6/6 ohms = R
(2) the current flow in a circuit when the resistance is 4 and 6 ohms respectly. i = 6/4 amps, i = 6/6 amps
