An amplifier is measured to have an internal resistance of 10 k , voltage gain of 100V/V and output resistance of 100 . Also, when a load resistance of 1 k is connected between the output resistance if found to decrease to 8 k . If the amplifier is fed with the signal source having an internal resistance of 2 k . Find Gm.

• A. 1 A/V
• B. 10 A/V
• C. 100 A/V
• D. 1000 A/V
