Ohm's law relates the volate V across a resistor, the electrical current I passing through the resistor, and the resistance R. In particular: V=IR. Ohm's law relates the volate V across a resistor, the electrical current I passing through the resistor, and the resista...
The current passes through a resistor in a circuit connected across a battery of the potential V is equal to the ratio of the supplied voltage and resistance. As we increase the potential of the battery, the current in the resistor directly increases. Thus, {eq}...

In general, current is measured as the voltage across a resistor. This resistor can be placed directly in the current path, but for the conventional ECN measurement this will inevitably lead to a voltage difference between the two working electrodes. While the resistor, and hence the voltage dro...
