E7G11
What absolute voltage gain can be expected from the circuit in Figure E7-3 when R1 is 3,300 ohms and RF is 47 kilohms?
- A.28
- B.14 (correct answer)
- C.7
- D.0.07
WhyThe circuit in Figure E7-3 with R1 at 3,300 ohms and RF at 47 kilohms has an absolute voltage gain of about 14. The Figure E7-3 circuit's absolute voltage gain equals RF divided by R1: 47,000 ohms divided by 3,300 ohms works out to approximately 14.2, which rounds to 14, answer B. The other figures don't match a correct division of this specific pair of resistor values.
