Voltmeter, ammeter, galvanometer, thermometer - tell the odd one out and give a proper explanation.
Understand the Problem
The question is asking which of the listed instruments (voltmeter, ammeter, galvanometer, thermometer) is different from the others and to provide an explanation for that categorization. The high-level approach would involve identifying the function of each instrument and explaining why one does not belong with the others.
Answer
Thermometer is the odd one out as it measures temperature while the others measure electrical parameters.
The odd one out is the thermometer because it is used to measure temperature, whereas the voltmeter, ammeter, and galvanometer are used to measure electrical parameters.
Answer for screen readers
The odd one out is the thermometer because it is used to measure temperature, whereas the voltmeter, ammeter, and galvanometer are used to measure electrical parameters.
More Information
Voltmeter, ammeter, and galvanometer are used to measure different aspects of electric current and voltage. In contrast, a thermometer measures temperature changes, which is unrelated to electricity measurement.
Tips
A common mistake is to misconstrue the purpose of each device, assuming they are all related to scientific measurements without distinguishing their specific fields.
