Question

Voltmeter is always connected in parallel across the points in electric circuit. Why

Answer 1

Answer:

In an electric circuit a voltmeter is always connected in parallel across the points because the voltmeter reduces the current passing in the circuit.

Hence there occurs a decrease in the potential difference the to be measured in the circuit.

Always voltmeter is connected in parallel than in series in an electric circuit.

Answer 2

Voltmeter is always connected in parallel across the points in electric circuit to help record the voltage across the resistor.

Explanation:

• A voltmeter is an electrical instrument which is used for the purpose of  measuring the potential difference between two points in an electric circuit.
• A voltmeter is always connected in parallel across the points in an electric circuit.
• The main purpose of the  voltmeter is to measure the voltage across a resistor or a load in circuit.
• A voltmeter is never connected in series, because in case of a voltage drop the voltmeter will not be able to give the proper reading , it will  not be able to record the correct voltage across the resistor.
• Same is the case with an ammeter which is an instrument that measures the current in a circuit. If it  is connected in parallel, then the current gets divided into different paths and the ammeter can no longer measure the actual current flowing through the resistor.

• Thus  a Voltmeter is always connected in parallel across the points in an electric circuit to help record the voltage across the resistor.
