How to find loading current in any op-amp circuit?

If I am connecting a dc source and an ac signal to a summing amplifier, will the ac source affect the dc source?

    Hey Arjun, 

    There is an analog engineer's circuit for this! This can be found via: ti.com > Design Resources > Design tools & simulation > Analog Circuits > Amplifier Circuits > Basic Circuits > Inverting Summer Circuit 

    The benefit here is that the design's calculations and simulation profile have already been completed for the ease of the customer.
    The TINA simulation is located in the "Design References," you may use the simulation profile to answer your question. 

    All the best,
    Carolina
