How does the input impedance of a field-effect transistor compare with that of a bipolar transistor?
A. An FET has high input impedance; a bipolar transistor has low input impedance.
B. One cannot compare input impedance without first knowing the supply voltage.
C. An FET has low input impedance; a bipolar transistor has high input impedance.
D. The input impedance of FETs and bipolar transistors is the same.
