Source sentences:
text: If the voltmeter has low resistance, the current passes through it, and the voltmeter gives the incorrect result.
text: The requisite factor in such voltmeters is that the resistance of plates of vacuum tube should be low so that it does not create variation in linear characteristics of plate voltage and current.
text: The resistance of the ammeter is low.
text: Whereas, the internal resistance of the voltmeter is very low so that the current from the circuit does not disturb the measuring of the voltmeter.
text: This can only be possible if the resistance on the ammeter is very low so as to ensure correct measurement of current in the circuit.
text: If the voltmeter has a low resistance,
text: Since S is low resistance, resistance of ammeter R A is very low and when it is connected in series in the circuits, it will not affect the current passing through the circuit.
text: Putting these two in parallel, the voltmeter will simply be reading the voltage across the ammeter and because the resistance is low the voltage (unless the current is very high) will be low also; possibly too low to register.
text: If the voltmeter has low resistance, it will draw an appreciable amount of current.
text: If the voltmeter has a low resistance, it will draw a substantial amount of current.
