Input Offset Voltage: It is the voltage that must be applied between the input terminals of an op-amp to null the outupt.
Does it mean that in ideal op-amp there is no output when differential voltage between terminals is zero. And in practical op-amp there is no output when the differential voltage is equal to the Input Offset Voltage?

Input Offset Current: The algebraic difference between the currents into the inverting and noninverting terminals is referred to as input offset current.
Input Bias Current: It is the average of currents that flow into the inverting and noninverting input terminals of the op-amp.
under what conditions are the current in the terminals measured?

Differential Input Resistance: It(often referred to as input resistance) is the equivalent resistance that can be measured at either the inverting or noninverting input terminal with other terminal connected to ground.
Doesn't the mismatching between terminals give different results at inverting and noninverting terminal?

In the multimeter we have two leads (red and black). If I connect the red lead with one terminal of the op-amp, where do i connect the black lead?
