Answer:
potential difference is work done to move one coulomb of charge fome one point to another in a circuit.
Voltmeter is device to measure it and it is always connected in parallel.
Current is time taken to move one coulomb of charge.
ammeter is device to measure it and it is always connected in series.
Explanation:
ohm law give its relationship
current is directly proportional to potential difference
resistance is also directly proportional to potential difference
temperature must be constant.
