3v, 5v and 7v are the three input voltage applied to the inverting input terminal of averaging amplifier. Determine the output voltage?

The output voltage (Vout) of an averaging amplifier can be calculated using the formula:

Vout = -(V1 + V2 + V3 + ... + Vn)/n

where V1, V2, V3, ..., Vn are the input voltages and n is the number of inputs.

In this case, the input voltages are 3v, 5v, and 7v. So, n = 3.

Substituting these values into the formula, we get:

Vout = -(3v + 5v + 7v)/3 = -15v/3 = -5v

So, the output voltage of the averaging amplifier is -5v.
