Infra-red detectors and optic lens, Physics

Assignment Help:

Infra-Red (IR) Detectors:  

An IR detector has an impedance of Z= (400+j200) ?  . During design  tests the detector  current  is measured  as  4  µA.

What  is  the output voltage of the detector?

Optic lens:  

Using a converging lens of focal length  f= 10 cm, we want an object  to appear on the screen  twice as big as  its original size.

Where  is  the object to be located in front of the screen (real image)?
