WebHow to measure current. Current can be measured using a device called an ammeter. Ammeters should always be connected in series with the part of the circuit where you wish to measure the current, as shown in the figure below. This is because current has to flow through the ammeter in order for it to read the value.

WebIn any design, if the redox process at electrodes will limit the current, the measured ionic current value is not a property of the membrane. Cite. 2 Recommendations. 20th Jun, 2016. WebThe electric current is measured in ampere. One ampere of current represents one coulomb of electric charge moving past a specific point in one second. 1 ampere = 1 coulomb / 1 second The conventional direction of an electric current is the direction in which a positive charge would move.

WebPower is defined as the rate energy ( \text U U) is transformed or transferred over time. We measure power in units of joules/second, also known as watts. An electric circuit is capable of transferring power. Current is the rate of flow of charge, and voltage measures the energy transferred per unit of charge.
