Why is a voltmeter connected in parallel?
Understand the Problem
The question is asking for the reasoning behind the connection of a voltmeter in a parallel configuration within an electrical circuit. This approach allows the voltmeter to measure the voltage across the components it is connected to, without altering the overall resistance of the circuit significantly.
Answer
To measure accurate voltage without affecting circuit resistance.
A voltmeter is connected in parallel to ensure it measures the voltage across two points accurately while minimizing the current through itself due to its high resistance.
Answer for screen readers
A voltmeter is connected in parallel to ensure it measures the voltage across two points accurately while minimizing the current through itself due to its high resistance.
More Information
Connecting a voltmeter in parallel ensures it measures the voltage drop across the component correctly, leveraging its high resistance to minimally affect the current and overall circuit resistance.
Tips
A common mistake is confusing the connections of voltmeters and ammeters; always remember voltmeters parallel and ammeters series.
