Why voltmeter has high resistance and ammeter has low resistances?

Question

Answer

Ammm bcuzzz.... voltmeter has High resistance as it is connected in parallel combination...so that it may not change the amount of current flowing through a circuit....whereas ammeter which is connected in series combination so that it gives accurate reading of current flowing through a circuit.... hope this helps..!!!!

Answer

Ammeter is used to measure the strength of current in an electric circuit, it is always connected in series with a circuit, hence its introduction should not change the current, so it has low resistance.,,,,,.... Voltmeter is an instrument to measure the potential difference  between two  points to which terminals of the instrument are connected.It is always connected in parallel to the circuit and its introduction does not change the pot. diff. to be measured, hence it may have high resistance.

Answer

Voltmeter has high resistance because if it has low resistance current will flow through it which can disturb reading. Ammeter has low resistance to flow around all current through it to get accurate reading

Answer

Voltmeter****-it doesn't 'draw' current through it.so it have high resistance!!!!

Answer

Reasons for high resistance in voltmeter:
- A voltmeter is designed to measure voltage across a circuit component, which requires a high level of resistance to prevent significant current flow through the meter.
- High resistance in a voltmeter ensures that it does not draw a significant amount of current from the circuit being measured, which could affect the accuracy of the voltage reading.
- The high resistance of a voltmeter allows it to measure the voltage drop across a component without altering the circuit's overall voltage.

Reasons for low resistance in ammeter:
- An ammeter is used to measure the current flowing through a circuit, so it needs to have a low resistance to allow the current to pass through it without significant impedance.
- Low resistance in an ammeter ensures that the current being measured flows through the meter, providing an accurate reading of the circuit's current.
- The low resistance of an ammeter allows it to be connected in series with the circuit, so the current flows through the meter itself to provide an accurate measurement.
In summary, the high resistance in a voltmeter is necessary to prevent current flow and accurately measure voltage, while the low resistance in an ammeter allows current to pass through for accurate current measurement. Each meter is designed with specific resistance levels to fulfill its intended purpose within an electrical circuit.
