Figure 1 shows the current output from a solar panel under constant, steady sunlight.

Figure 1: A graph of current in amperes on the y-axis against time in seconds on the x-axis. The line on the graph is perfectly horizontal at a constant current of 1.5 A, showing a steady direct current (d.c.)

Explain why a transformer will not work to change the voltage with the input current shown in Figure 1.
