Question 56002: A constant voltage is applied to a circuit that has a variable resistor. The current varies inverseley as the resistance. At a resistance of 6 ohms, the current is 10 amperes. Find the current when the resistance is 12 ohms.

You can put this solution on YOUR website! A constant voltage is applied to a circuit that has a variable resistor. The current varies inverseley as the resistance. At a resistance of 6 ohms, the current is 10 amperes. Find the current when the resistance is 12 ohms.
-----------
current = k/resistance
c=k/r ; need to find "k"
10=k/6
k=60
So, equation is c=60/r
If r=12 ohms,
c=60/12
c==5 amps
