Answer 1

The input voltage applied across the input terminals to have zero output voltage is called  input offset voltage.

Explanation:

The input voltage applied across the input terminals to have zero output voltage is called

(A) Input offset voltage

(B) Output offset voltage

(C) Input offset current

(D) none of these​

Solution:

• The voltage that is applied across the two input terminals of an Op-amp in order to get zero output voltage is called input offset voltage.
• In an Op-amp, an ideal output value is achieved when the inputs are grounded and they help out to obtain the desired values.
• While in reality, the dc potential between input terminals is slightly different from the ideal value.
