1.

In a single state transistor amplifier, when the signal changes by 0.02 V, the base current change by 10uA and collector current by10 mu A. If collector load R_c = 2k Omegaand R_L = 10k Omega , Calculate : Effective ac load,

Answer»

SOLUTION :EFFECTIVE AC load,
` R_(AC ) = R_C||R_L`
` thereforeR_(AC )= ( 2 xx 10 )/( 2+10) = 1.66k OMEGA`
