For a transistor amplifier, the voltage gain
remains constant for all frequencies.
is high at high and low frequencies and constant in the middle frequency range
is low at high and low frequencies and constant at mid frequencies.
None of the above.
The graph shows the variation of current with voltage for a p-n junction diode. Estimate the dynamic resistance of the diode at \( V = -0.6 \) V.
In the given circuit, the equivalent resistance between points A and D is:
