Question:
Which one of the following statements is NOT correct?
Which one of the following statements is NOT correct?
Options:
- a) An ammeter is always connected in series in the circuit to measure the current.
- b) A voltmeter is always connected to parallel in a circuit to measure the voltage.
- c) A voltmeter has a high resistance and an ammeter has a low resistance.
- d) A voltmeter has a low resistance and an ammeter has a high resistance.
- a) An ammeter is always connected in series in the circuit to measure the current.
- b) A voltmeter is always connected to parallel in a circuit to measure the voltage.
- c) A voltmeter has a high resistance and an ammeter has a low resistance.
- d) A voltmeter has a low resistance and an ammeter has a high resistance.
correct answer : d)
Explanation:
A voltmeter has a very high resistance and is always connected in parallel. An ammeter has nearly zero resistance and is connected in series. Therefore statement (d) is incorrect.
A voltmeter has a very high resistance and is always connected in parallel. An ammeter has nearly zero resistance and is connected in series. Therefore statement (d) is incorrect.
