What is high resistance and low resistance?
Low resistance lets electrons through easy, and high makes it harder for them to pass. Basically electricity is harder to flow through high resistance and vice versa.
Why are there more than two terminals on some ammeters and voltmeters?
A volt meter needs a high internal resistance not to influence the measurement, an ammeter needs a low internal resistance. Sometimes the easiest way to make that happen is to have different connectors.
Why is the resistance of volt meter very high?
So it doesn't effect the circuit being tested. If a low impediance or resistance meter were inserted in the circuit, voltages may drop and effect the accuracy of the test. Any voltmeter will use some power from the circuit to make a reading. A "high impediance voltmeter" will use very little power from the circuit so the voltage reading will be as accurate as it can be.
What kind of meter is created when is shunt is added to a galvanometer?
A galvanometer with a low resistance shunt in parallel makes an ammeter.
How does the loading effect of a voltmeter in a high-rsistance circuit compare to the loading effect in a low-resistance circult?
The voltmeter has an internal resistance, which should be as high as possible. As this resistance draws current from the circuit under test, it will affect circuit operation. This is more pronounced in a high impedance circuit because the current drawn flows through higher resistances.
Why it is essential for voltmeters to have a very high resistance?
if the resistance of the meter is low that will act as a parallel load effecting the reading. If the meter can be made with infinite resistance then the meter will not effects the actual reading.
Why meter bridge can't be used to measure low resistance and high resistance?
used to measure low Resistance since it must reach a null.
Is graphite a high resistance or low resistance of electricity?
Graphite is low resistance of electricity...
Do meters usually have a high or low internal resistance?
It depends on the application. Voltmeters have a high internal resistance, while ammeters have a low internal resistance.

What wire connection better high or low resistance?
Usually low resistance is better.
Which has the thickest filament - a high-resistance or a low-resistance bulb?
A high-resistance bulb typically has a thicker filament compared to a low-resistance bulb. The thicker filament in a high-resistance bulb can withstand the greater heat generated by the increased resistance, resulting in a longer lifespan for the bulb.
If a multimeter reads zero on the ohm scale is this high or low resistance?
zero is low resistance
How can you get low viscoSity and high resistance?
You get low viscosity with thin liquids like water that flow easily. Low viscosity means the liquid has low resistance. You get high resistance when you have liquids that flow slowly like honey and syrup, which means high viscosity.
Does a good connector has a high resistance?
low
What is the difference between high impedance and low impedance?
The difference between high impedance and low impedance is the amount of resistance in an electrical circuit. High impedance means there is a high level of resistance, which limits the flow of current. Low impedance means there is a low level of resistance, allowing for a greater flow of current.
