1. Determine the power supplied by the leftmost element in the circuit 2. Relevant equations Power = Voltage ( Current) 3. The attempt at a solution As power = voltage (current), that is the equation that will be used. The leftmost element shows a current of 2 AMPS entering through the negative node and a voltage of 2V. Therefore the power ought to be : P = (-2A)(2V) = -4W I just wanted to know if I did this correctly as we do not have a solutions manual for the book we are using.
