Use the Figure above for problems 2324 For the circuit above

Use the Figure above for problems 23-24. For the circuit above, the formula for voltage again is best described by which answers? (1 + R_F/R_1) -(1 - R_F/R_1) - R_F/R_1 R_F/R_1 None of the above. If R_L = 10 K Ohm, R_F = 40 K Ohm and V_IN = 2 V, which answer best represents V_OUT ? 10 V -10 V 6 V -6 V None of the above.

Solution

non inverting op amp

V0=VI(1+RF/RI)

GIVEN RF=40K OHM

RI=10 KOHM

VIN 2

VO=(2)*(1+(40/10))

10V
