Resolution is the smallest change that can be measured by an instrument.
Accuracy is the closeness of a measured value its 'true' value.
Precision is essentially related to repeatability when you try to do the same measurement a few times.
Forget precision for now. We know the terms resolution and accuracy mean different things and have different definitions. But that is not to say they are not related/coupled where one influences the quality of the other?
Is it true to say a low resolution instrument affects the accuracy with which you report a value. Say a beaker has increments of 0.1ml and you read off 2.3ml to your best of your ability, but while only God truly knows its really 2.2641ml exact. It is ultimately the resolution affecting the accuracy of the value being reported? So when someone reports 2.3ml it is inaccurate.
So essentially, is it true to say resolution of measurement almost always affect accuracy?
