Question 874415: Anyone can help me?
The current in a simple electrical circuit varies inversely as the resistance. If the current is 66 amps when the resistance is 7 ohms, find the resistance when the currents 30 amps?
A.210 ohms
B. 1/210 ohms
C. 15.4 ohms
D. 4.1 ohms

You can put this solution on YOUR website!
I = k/R
66amps = k/7ohms
462V = k
I = 462V/R ***
If I = 30amps
30amps = 462V/I
I = 462V/30amps = 15.4ohms
