Hi,
The current (I) varies directly as the voltage (V) in an electric circuit. 
If the current is 4 amperes when the voltage is 100 volts, 
find the current when the voltage is 75 volts.
  I=kV
  4 = k(100)
 .04 = k
  I = .04(75V) = 3 amperes  (Notice when voltage is less, current is less)
Wish You the Best in your Studies.
