Question

Tell the odd one one out. Give proper explanation.

Voltmeter, Ammeter, galvanometer, thermometer.

Answer 1

The thermometer is the odd one.

All the other belongs to the electric circuit.

The voltmeter is used to measure the potential difference.
The galvanometer is used to measure the current.
An ammeter is used to measure current in amperes.

The thermometer is used to measure temperature

So thermometer is the odd one.

Hope this helps you.

Answer 2

ANS."THERMOMETER" BECAUSE OTHER OBJECTS ARE BEING USED FOR MEASURING SOMETHING RELATED TO ELECTRICITY BUT THERMOMETER IS USED TO MEASURE TEMPERATURE.

● Voltmeter is used to measure electricity potential in volts.

● Ammeter is used measure electric current in amperes

● Galvanometer is used to measuring and detecting small electric currents.
