With a current strength of I₁ = 5A, the external circuit of the source consumes power P₁ = 9.5W. If the resistance of the external circuit R₂ = 0.225 Ohm, the power consumption P₂ = 14.4 W. What is the maximum power that an external circuit can consume from this source? What is the efficiency of the source?
