Section 1.4: Amplifiers 1.45 Various amplifier and load combinations are measured as listed below using rms values. For each, find the voltage, current, and power gains (A,,A,, and A,, respectively) both

as ratios and in dB: (a) v = 100 mV, i, 100 μA, 10 V, R₂ = 100 2 (b) = 10 μV, i,= 100 nA, vo = 1 V, R₂ = 10 k = 1 V, i = 1 mA, vo = 5 V, R₂ = 102 (c)
