In a common emitter configuration `I_c=13.5 mA, I_b=150 mu A`. Compute `I_e` and `beta`.

A transistor connected in common emitter configuration has input resistance R_("in")=2 K Omega and load resistance of 5 K Omega . If beta=60 and an input signal 12 mV is applied , calculate the resistance gain.

In a common-emitter mode of transistor d.c. current gain is 20 and the emitter current is 7 mA. Calculate base current

For a common base amplifier, emitter current is 5.2 mA and base current is 0.22 mA. Find the current gain of the amplifier.
