Ideal Voltmeter has an infinite resistance so it won't draw current from the circuit, but in real life ideal voltmeter doesn't exist.

What is meant by an ideal fuel?
An ideal fuel is a fuel which is cheap, easily available, easily transportable, has low ignition temperature and has high calorific value.
What is an imaginary gas that conforms perfectly to the kinetic molecular theory callled?
That's called an "ideal gas". The behavior of real gases is quite similar to an ideal gas, except when the pressure is too high, or the temperature too low.That's called an "ideal gas".

Which instrument can measure static electricity having a potential difference as low as 0.1 volts?
electroscope
Is the boyles law is valid at high temperature?
Yes, if the pressure is low.
Is it possible to apply voltmeter across a variable resistor?
Of course. A good voltmeter can be applied across anything, since its impedance is high and its presence has no effect on the operation of the circuit. When it's connected across a variable resistor, the voltmeter most likely reveals a changing voltage as the resistor is varied.
Does a Digital Voltmeter have a high or low input impedance?
Digital voltmeter has high input impedence.
Ideal universal high resistance voltmeter?
The ideal, or theoretical, voltmeter has infinite resistance, which means that, at any measured voltage, there is no current through the voltmeter. In the practical world, this is impossible, but there are high resistance voltmeters that minimize the error introduced by drawing a current from a circuit. A typical digital voltmeter has 10 to 20 megohms of resistance, and there are high performance versions that can have thousands of megohms of resistance, or more.
What is voltmeter with a broad band width has noise and sensitivity?
high noise level and low sensitivity
What instrument measures VDC?
A DC voltmeter is ideal.
Why does voltmeter practically not consume any electric energy from the electric circuit?
The resistance used in a voltmeter is extremely high when measuring voltage, which is why the current is low (I = E/R).
What should be the resistance of an ideal voltmeter?
infinity- so that all the voltage is measured across the component instead of losing some in voltometer circuitry
Why is ideal resistance of a voltmeter infinity?
generally voltmeters are connected in parallel in the circuit.If the voltmeter resistance is lower as it increases the current rating,because by connecting parallel we are decreasing the resistance,so if the voltmeter resistance is not too much higher it leads to burning of the meter,For that we can conclude that the in ideal the voltmeter has infinite resistance.
What will happen if a voltmeter has a low shunt resistance instead of having high shunt resistance?
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.
When is H2 an ideal gas?
low pressure and high temperature
What is the use of universal high resistance voltmeter?
A voltmeter must have a very high resistance to measure voltage. A voltmeter is placed in parallel with the element that you are measuring. If the voltmeter has a low internal resistance, then all of the current will flow through the voltmeter instead of the element. You want all of the current to flow through the element, to get an accurate reading of the voltage. Conversely, an ampmeter must have zero resistance, because it is placed in series with the element.
What condition cause deviations from the ideal gas?
High pressure, and low temperature.High pressure, and low temperature.High pressure, and low temperature.High pressure, and low temperature.
When does a real gas display the most ideal behavior?
This is a gas having a high concentration.
