“Electrical resistance in microbial fuel cell circuits can be analyzed using Ohm's law (V = I·R).”

The statement is well supported by standard microbial fuel cell practice. Peer-reviewed reviews and methods papers routinely use Ohm’s law to calculate current through known external resistors and to estimate effective resistance, especially in the linear ohmic region. MFCs can depart from simple ohmic behavior outside that region, but that limits precision rather than the basic applicability of V = I·R.

“Ohm's Law states that voltage equals current multiplied by resistance, expressed as V = IR.”

Reliable physics and engineering references define Ohm’s Law as V = IR—voltage equals current multiplied by resistance. The statement accurately reproduces the law’s standard formulation and is consistently confirmed across independent sources. While the law applies only to materials that behave ohmically under stable conditions, that limitation does not alter what the law itself states.
