4. In an electrical circuit it is known that the voltage V varies as the current I

(ie. that V is directly proportional to 1). It is also known that V = 36

when I = 8.

a Find a formula for V in terms of I.

b Find V when I = 14.

с Find / when V = 27.

    Step-by-step explanation:

    V∝I

    V=kI

    36=k*8

    k=36/8

    k=4.5

    a. V=4.5I

    b. V=4.5*14

    V = 63

    c. 27=4.5I

    I=27/4.5

    I = 6
