It is the current amplifier gain?
Av
Ai
Ap
All of the mentioned
The ________ is a logarithmic unit (base 10) of measurement that has no units.
decbel
decibel
bels
Bel
To compute amplifier gain in current and voltage it must be
input / output (input divided by output)
output / input (output divided by input)
Output + Input
output*input
Determine the amplifier gain when the output signal is 10v and 133mA, and the input signal is 88mV and 12mA.
Av = 1.51 and Ai = 111.0833
Ai = 1.51 and Av = 111.0833
Ai = 113.64 and Av = 11.0833
Av = 113.64 and Ai = 11.0833
