vampirchik [111]

Explanation:

Power = work / time

Power = force × distance / time

P = (35 lbf) (6 in) / (0.7 s)

P = 300 lbf in/s

an amplifier has an input resistance of 100k a short-circuit transconductance of 10 mA/V and an output resistance of 100k. Find

Vlada [557]

Answer:

The open circuit voltage gain is $A_{vo}=-10^{3}$

Explanation:

Given data is input resistance of an amplifier is $R_{in}=100k$ Ω and output resistance of an amplifier is $R_{o} =100k$ Ω.

Trans conductance of an amplifier is $g_{m}=10mA/V$

Thus Open circuit voltage gain is

$A_{vo} =-g_{m}R_{o}$

$A_{vo}=-10$ × $10^{-3}$ ×100× $10^{3}$

Since 1m= $10^{-3}$ and 1k= $10^{3}$

Thus,

$A_{vo}=-1000$

$A_{vo}=-10^{3}$
