A particular inverting amplifier with nominal gain of -100 V/V uses an imperfect op amp in conjunction with 100-k-ohm and 10-M-ohm resistors.

The output voltage is found to be +9.31 V when measured with the input open and +9.09 V with the input grounded.

a) What is the bias current of this amplifier" In what direction does it flow?

b) Estimate the value of the input offset voltage.
