Answer» Right answer is (d) can transmit small bioelectric signals even after getting exposed to large pulse of energy To explain: Polarizable electrodes usually employ stainless steel and are used for resting ECG or other situations where there is small likelihood that the electrode would be exposed to a large pulse of energy (such as defibrillation discharge) in which case they would retain a residual charge, become polarized, and will no longer transmit the relatively small bioelectric signals, thus become useless. |
