Calculate the gain of the non-inverting amplifier shown in Fig.P.18.5.  Answer ( 5 )




Given:



Resistance 1 = `\R_1` = 10 kΩ = 10x10³ Ω

Resistance 2 = `\R_2` = 40 kΩ = 40x10³ Ω


To Find:

Gain = `\G`  ?



Solution:


The formula for Gain "`\G`" is

`\G` =  1 + `\frac {R_2}{R_1}`

By putting values

`\G` =  1 + `\frac {40x10³ Ω}{10x10³ Ω}`

`\G` =  1 + 4

`\G` =  5 -----------------Ans
