Name a device that helps to maintain a potential difference across a conductor?
battery helps n maintaing d potential difference.
a voltmeter is used to measure d potential diference n a circuit
Battery helps in maintaining potential difference across a conductor.
IT IS BATTERY.
voltmeter is the instrument used to MEASURE POTENTIEL DIFF. AND NOT MAINTAIN P.D
A BATTERY HELPS IN MAINTAINING POTENTIAL DIFFERENCE ACROSS A CONDUCTOR.
A source of electricity such as cell, battery, power supply, etc. helps to maintain a potential difference across a conductor.
but voltmeter is used to measure the potential difference acrosss the two ends of the conductor
