Emitter Follower CC
Product Code : JA-AET-1450
The emitter follower trainer is a common-collector (CC) amplifier board for measuring voltage gain, input impedance and output impedance in electronics practicals. It is built around an NPN transistor with an internally connected +9 V DC, 50 mA IC-regulated supply, and is used with an audio frequency generator, a decade resistance box and an AF millivoltmeter (SKU JA-AET-1450).
