Consider the circuit shown in the above figure. The voltages across branches are given by $V_A = 13 \text{ V},$ $V_C = 13 \text{ V},$ $V_D = 3 \text{ V},$ $V_E = -6 \text{ V},$ and $V_F = 16 \text{ V}.$ The currents flowing through branches are given by $i_ A = 12 \text{ A},$ $i_C = 24 \text{ A},$ $i_D = 6 \text{ A},$ $i_E = -6 \text{ A},$ and $i_F = 6 \text{ A}.$ Find the values of the power supplied by branch $B.$
