    2. Relevant equations


    3. The attempt at a solution

    for What will happen if you cut the wire at position B?

    I think The light bulb will become dimmer, but not go off. Am I correct?

    for What will happen if you cut the wire at position D?

    I think The light bulb will go off. (since the bulb was disconnected from the circuit) Am I correct?
