In CE transistor amplifier, the audio signal voltage across the collector resistance of 2 k is 2 ~V . If the base resistance is 1 k and the current amplification of the transistor is 100, the input signal voltage is

Step-by-step solution

Given : Voltage across the collector V ₀=2 V ; collector resistance, R _ c =2 10³ ; Base resistance R _ B =1 10³ ; Input signal voltage, V _ i =? array l V ₀= I _ C R _ C =2 I _ C = 2 2 10³ =10⁻³ ~A Current gain = I _ C I _ B =100 I _ B = I _ C 100 = 10⁻³ 100 =10⁻⁵ ~A ~V _ i = R _ B I _ B V _ i =1 10³ 10⁻⁵ V _ i =10⁻² ~V V _ i =10 mV array
