Refer to the circuit below for the following 4 problems. Find the voltage at A, B and C (relative to shown ground). What is the voltage V_x How much power is being provided by the element between points B and C? (Explain or show work).

since there is no current flowing through the element between B & C is zero, there is no power delivered between the element B and C.
