The electric power P (in W) dissipated in a resistance R (in ) is given by P

Question:

The electric power P (in W) dissipated in a resistance R (in Ω) is given by P = Ri2, where i is the current (in A) in the resistor. Find the equation for the total power of 64 W dissipated in two resistors, with resistances 2.0 Ω and 8.0 Ω, respectively, and with currents i1 and i2, respectively. Sketch the graph, assuming that negative values of current are meaningful.
