Is the voltage V_s in Figure 1 supplying or absorbing power and how much?

Solution

1.

From the circuit, we can observe that V_s=8 V and current across Vs is 6A. Current is flowing anode to canthode terminal of V_s source. So V_s is supplying power.

P_s=V_s*I_s= 8*6=48 W

Therefore, 48 W is power supplied by the V_s.
