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.
but voltmeter is used to measure the potential difference acrosss the two ends of the conductor
IT IS BATTERY.
voltmeter is the instrument used to MEASURE POTENTIEL DIFF. AND NOT MAINTAIN P.D

A source of electricity such as cell, battery, power supply, etc. helps to maintain a potential difference across a conductor.
A BATTERY HELPS IN MAINTAINING POTENTIAL DIFFERENCE ACROSS A CONDUCTOR.
device for measuring potential difference
guys............battery helps in maintaining the potential difference and ur loving volt meter is used to measure it.............
Voltmeter help in maintaining a potiential difference across a conductor.
