Hello experts! Image of Differential Amplifier is given below. Here in diff amp both transistor have same characteristics. Even +VCC and -VEE are of same magnitude. Everything is same. Hence, their RE and RC are also same. 1)If both emitter and collector resistance of both transistor are same then why only RE is combined why not RC? RC for both are shown individually at both collectors even both collectors have same magnitude of resistance. Why? 2)And both supply voltages VEE and VCC are same. Is it correct? Thanks in advance.
