For a transistor, in a common emitter arrangement, the alternating current gain b is given by [DPMT 2004]

\[\beta ={{\left( \frac{\Delta {{I}_{B}}}{\Delta {{I}_{C}}} \right)}_{{{V}_{C}}}}\]

\[\beta ={{\left( \frac{\Delta {{I}_{C}}}{\Delta {{I}_{B}}} \right)}_{{{V}_{C}}}}\]

\[\beta ={{\left( \frac{\Delta {{I}_{C}}}{\Delta {{I}_{E}}} \right)}_{{{V}_{C}}}}\]

\[\beta ={{\left( \frac{\Delta {{I}_{E}}}{\Delta {{I}_{C}}} \right)}_{{{V}_{C}}}}\]
