a) Most op-amps are powered by bipolar power supplies. What is the principal advantage of this particular feature?
b)The input stage of an op-amp responds to the voltage (V+ -V-). Why is the op-amp designed to be sensitive to a voltagedifference rather than to a voltage measured relative toground?
c)Given that I-in(currrent in)=0 from the V-in source for anon-inverting op-amp, from where does the current flowing out ofthe Vout terminal come?
