opamp lm318 output problem.

hi,View attachment 64941


i am using opamp lm318 for non inverting amplifier but it doesn't give proper output. i am attaching my ckt here.
if input is 1V and gain is 201 than output is 2v. VCC is 15V.


please help me to solve it.

If input is 1v and gain is 201 then output is 201v with an ideal op-amp. An LM318 is not ideal.
Irregardless of the gain, the LM318's output voltage will always be less than the Vcc & Vee power supply values. Some op-amps are very,very close to Vcc & Vee others are not close at all. Most analog circuits want +/- 15v supplies in order to guarantee operation at 10v.
