Resistance of an ideal voltmeter is Infinite and that of an ammeter is zero.
- What resistance is ammeter?
- What is resistance of a voltmeter?
- Why is resistance of voltmeter high?
- What is the resistance of voltmeter and why?
- What is difference between ammeter and voltmeter?
What resistance is ammeter?
For the ideal case, resistance of an ammeter is zero. Therefore, ammeter is made by connecting resistance in parallel with the coil of a galvanometer. This parallel resistance is called shunt.
What is resistance of a voltmeter?
The internal resistance of the ideal voltmeter is infinity since it should not allow any current to flow through the voltmeter. Voltmeter measures the potential difference, it is connected in parallel. Was this answer helpful?
Why is resistance of voltmeter high?
A voltmeter measures the voltage difference between the two different points (say, on different sides of a resistor), but it should not change the amount of current going through the element between these two points. So it should have very high resistance so mat it doesn't draw current through it.
What is the resistance of voltmeter and why?
A voltmeter is an instrument used for measuring the electric potential difference between two points in an electric circuit. It is connected in parallel. An ideal voltmeter has infinite resistance and it is an open circuit.
What is difference between ammeter and voltmeter?
Both of these devices are used in electric circuits but the major difference between a voltmeter and an ammeter is ammeter comes in handy for measuring the flow of current whereas the voltmeter comes in handy for measuring the voltage or emf across two points in an electric circuit.
