For the multi-stage amplifier circuit in Fig. 2.14, Let 15CCV V, 1150R K, 215R K, 20CR K, 12ER K, 215ER K. Determine the values of the DC voltages 1CV, 1BV, 1EV, 2BV, 2EV, and CV. What is the small signal voltage gain? If a 20K load is attached to the output, what is the voltage gain?

Explanation:

Voltage gain  = Voltage out (Vcc)/Voltage in) this will be noted around the load 20 K as specified by the question. This is the only information that can be given since diagram was not included.

when a device is used in a circuit in which the voltage is 81 v, the current flowing through the device is 3 a. what is the resistance of the device?

a. 27 ω

b. 40.5 a

c. 243 ω

d. 243 a

the correct answer is a. 27

a. are
