Question

question #15: which of the following devices is used to measure the potential difference across a load?

voltmeter
ohmmeter
ammeter
spectrometer

question #16: current is measured as which of the following?

the amount of time it takes for 1 c of charge to pass a point
the amount of energy per unit of charge
the amount of charge that passes per unit of time
the change in electrical potential per unit of time

Explanation:

Identify potential difference measurement

Potential difference is measured in volts. A voltmeter measures this across a load.

Define electric current

Current is the flow rate of electric charge. It is charge passing per unit time.
