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.
