A transistor has h_{fe} = 150 and h_{ie} = 1.5 kΩ.
Assuming that h_{re} and h_{oe} are both negligible, determine the value of load resistance required to produce a voltage gain of 200.

Re-arranging A_v=\frac{h_{fe}\times R_L}{h_{ie}} to make R_L the subject gives:

R_L=\frac{A_v\times h_{ie}}{h_{fe}}

For a voltage gain of 200 the value of load resistance can be determined from:

R_L=\frac{200\times 1.5 \ k \Omega }{150} =2 \ k\Omega
