Question

In a circuit, voltmeter is always connected in ______?

1. Series
2. Parallel
3. Ether scenes of parallel
4. Trangular

Answer 1

Correct Answer - Option 2 : Parallel

CONCEPT:

Measuring instruments are:

Properties	Ammeter	Voltmeter
Measures	It is a device used to measure current and is always connected in series with the ‘element’ through which current is to be measured.	It is a device used to measure potential difference and is always put in parallel with the ‘circuit element’ across which potential difference is to be measured.
Resistance value	The ideal resistance of the ammeter is zero	A voltmeter is said to be ideal if its resistance is infinite, i.e., it draws no current from the circuit element for its operation.

EXPLANATION:

• The devices connected in parallel have the same potential difference across them.
• So, in order to calculate the potential difference across a device, the voltmeter must be connected in parallel.
