Answer 1

Explanation:

Current is measured with an ammeter, connected in series.

Answer 2

The correct answer is OPTION 1: Potentiometry.

• The electric parameters that are measured are what classify electroanalytical processes.
• The most often used electroanalytical processes include potentiometry, coulometry, conductometry, electrogravimetry, voltammetry, polarography, and amperometry.
• The names of the procedures are based on the electric property or units that are being measured.
• Potentiometry is a method of measuring electric potential or voltage while maintaining a steady electric current between electrodes.
• Amperometry is a method of measuring electric current (amperes) while keeping the voltage constant.
• Conductometry measures conductance (the ability of a solution to convey an electric current) while maintaining a stable alternating-current (AC) voltage between the electrodes.
