Explanation of question 17

An electronic voltmeter normally has

  1. high input impedance and high sensitivity
  2. high input impedance and low sensitivity
  3. low input impedance and high sensitivity
  4. low input impedance and low sensitivity

The answer is :- 1 The electronic voltmeter possesses a high impedance and high sensitivity. Its ‘loading effect’ on a circuit is therefore negligible.
