Physics Help VERY URGENT!!!!!!!!!!?

For the circuit in the figure below, answer the following. (Let V = 5.80 V, and R = 12.1 Ω.) 

(a) What is the direction of the resulting current?

clockwise? OR counterclockwise?    

(b) What are the following potential differences?

VW − VZ = _______ V 

VX − VW = ________V 

VX − VY =  ________V 

VZ − VY =  ________V 

(c) If we define the electric potential at the negative terminal of the battery to be zero, what are the electric potentials at the following?

point W ______V 

point X ______ V 

point Y ______ V 

point Z ______ V

    conventional current flows CW

    electron current flows CCW

    (b) What are the following potential differences?

    VW − VZ = 0 V 

    VX − VW = +5.8 V 

    VX − VY = 0 V 

    VZ − VY = –5.8 V 

    (c) If we define the electric potential at the negative terminal of the battery to be zero, what are the electric potentials at the following?

    point W 0 V 

    point X +5.8 V 

    point Y +5.8 V 

    point Z 0 V 

    (d) What is the current through the resistor?

    I = E/R = 5.8 v / 12.1 Ω = 0.479 A 

    What is the current through wire XY? 0.479 A

    What is the current through the battery? 0.479 A

    I = V/R = 5.8/12.1 = 0.48 A flowing from + to minus , i.e. CW according to r sketch

    Vyz = Vxw
