Prove that in a common-emitter amplifier, the output and input differ in phase by 180°.In a transistor, the change of base current by 30μA produces change of 0.02 V in the base-emitter voltage and a change of 4 mA in the collector current. Calculate the current amplification factor and the load resistance used, if the voltage gain of the amplifier is 400 . 📲PW App Link - https://bit.ly/YTAI_PWAP 🌐PW Website - https://www.pw.live
