  2. I don't agree with your answer. Why not use some numbers and see what happens. For example, E = 100, I = 50; R = ?.
    Then E = 100 and I = 50; R = ?. The general rule is
    E = IR so R = E/I. If I is constant than R = E*(1/k); therefore, if E goes up then R goes up. If E goes down then R goes down.

  4. R=v/I
    =100/50
    =2 ohms
