The transformercoupled class A amplifier has the lowest effi

The transformer-coupled class A amplifier has the lowest efficiency rating of all the class A amplifiers. True False A circuit like the one in Figure 1 has values: V_cc = 10 V, l_1 = 450 mu_A, and I_cq = 10.55 mA How much power is the circuit drawing from the dc power supply? 4.5 mW 1.21 mW 110 mW Cannot be determined from the information given.

Solution

Power = Voltage*Current

P = Vcc*(I₁ + I_cq )

P = 10*(0.45 mA + 10.55 mA )

P = 10*(11 mA)

P = 110 mWatt

OPTION C IS CORRECT
