A signal of 30 mV is applied to a common emitter transistor amplifier circuit. Due to this the change in base current and the change in the collector current are 20 μ A and 2 mA respectively. The load resistance is 15 kΩ . The trans conductance of the transistor is
(1) 0.032 mho
(2) 0.067 mho
(3) 0.15 mho
(4) 15 mho
