  • SRC A voltmeter has high resistance , if connected in series it will increase of circuit and reduce the current in the circuit
  • SRC A voltmeter has high resistance , if connected in series it will increase of circuit and reduce the current in the circuit
  • SRC A voltmeter has high resistance , if connected in series it will increase of circuit and reduce the current in the circuit
  • SRC A voltmeter must have a very high resistance so that it does not affect the voltage level when connected to a circuit .
  • SRC A voltmeter should have a very high resistance relative to the circuit resistance , at least 100 times for a 1 % error .
  • SRC Ask your students why a voltmeter should have a very high resistance ( many thousands or millions of ohms ) between its test leads .
  • SRC Because of the way they are connected , the ammeter needs to have a very low resistance while the voltmeter needs to have a very high resistance .
  • SRC If the switch was open the current would be forced to travel through the voltmeter which has very high resistance and the reading would be that of the applied voltage .
  • SRC In other words , a voltmeter should have a very HIGH resistance .
  • SRC So really the requirement that a voltmeter have a high resistance is a consequence of the way in which resistances are added when placed in parallel .
  • SRC So , it should have very high resistance so that it does n't " draw " current through it .
  • SRC So , it should have very high resistance so that it does n't " draw " current through it .
  • SRC So , it should have very high resistance so that it does n't " draw " current through it .
  • SRC The voltmeter should have a very high resistance so that on connecting it in the circuit , there is negligible change in the circuit resistance ( and hence the circuit current ) .
  • SRC Why Voltmeter has High Resistance ?
  • SRC the voltmeter is connected in parallel Voltmeters must have a HIGH resistance
