The power company uses a step-up transformer to prepare electric power for delivery to a distant city. The secondary coil of this transformer has many more turns than its primary coil. As a result, the transformer's secondary circuit
A. has a much higher current but a much lower voltage than its primary circuit.
B. has a much lower voltage and a much lower current than its primary circuit.
C. has a much higher voltage but a much lower current than its primary circuit.
D. has a much higher voltage and a much higher current than its primary circuit.
