There are electric showers on the market with different power ratings, which represent different consumptions and costs. The power (P) of an electric shower is given by the product between its electrical resistance (R) and the square of the electrical current (i) flowing through it. The consumption of electrical energy (E), in turn, is directly proportional to the power of the device.
Considering the characteristics presented, which of the following graphs represents the relationship between the energy consumed (E) by an electric shower and the electrical current (i) flowing through it?
(A) [graph A]
(B) [graph B]
(C) [graph C]
(D) [graph D]
(E) [graph E]
