The purpose of a voltmeter is to indicate the potential difference between two points in a circuit.When a voltmeter is connected across a circuit, it shunts the circuit. If the voltmeter has a low resistance,it will draw a substantial amount of current. This action lowers the effective resistance of the circuit andchanges the voltage reading.
A: There is no zeroing resistor the leads resistance are the zeroing resistor. there is however a pot where the zero can be accomplished by adjusting the current flow out of the meter to measure the voltage to determine the resistance. that pot is an adjustment to compensate for an old internal battery drift. If not changed periodically it may become a useless meter because zero cannot be achieved
B - Dynamic resistance
Parasitic resistance is resistance that you encounter in a circuit board or integrated circuit but not included in the original design -- an undesirable, unintended consequence of putting a concept into manufacturing. Since parasitic resistance does exist, you need to estimate its value and make sure the design still functions as intended. An example of parasitic resistance is the resistance of the traces in a circuit board or metal interconnects in an IC, the purpose of which is to connect components electrically according to the circuit diagram, but these connecting structures are not ideal. These connecting structures most likely also add parasitic capacitance and inductance to your design and, if substantial, should be included in your design (back-annotation) accordingly.
the purpose of the LRA is to turn the Uganda into a theocracy
to investigate change in resistance as temperature is varied
the purpose of it is it integrates schools

No, but it has resistance. Everything has resistance to current flow. It's sole purpose is not to resist current. It likely has resistors in it though.
The Carabinieri are the military police of Italy. Their original purpose was security and fraud resistance and they are noted for their mounted regiment

Because the main purpose of a toaster is to radiate heat. In order to generate heat from electric current, resistance is required in the circuit.
The colored bands on a resistor indicate its resistance value and tolerance. By interpreting the color code, you can determine the resistance value of the resistor and the range within which the actual resistance may vary. This helps in identifying, sorting, and using resistors in electronic circuits.
A nose cone helps to prevent air resistance also it can hold a parachute.
Corrosion resistance is the first thing that comes to mind.
This is a Resistors,who's resistance decrease when light energy falls on its surface gradually.
