At a minimum threshold, how many milliamps of current through the body produces a condition where most people would experience respiratory paralysis and be unable to breathe while still in contact with the energized conductor?

Question 1 of 29218

🔍 Key Concepts

• Human body reaction to electrical current at different milliamp (mA) levels • Difference between "can feel it / painful" vs. "can’t let go" vs. "respiratory paralysis" • Progression of effects: perception -> muscle control loss -> breathing/heart effects

💭 Think About

• Which current range is typically associated with just feeling a tingle or mild shock, without losing control? • At what approximate current range do you lose the ability to let go, but are still able to breathe? • What higher current level is generally associated with the chest muscles locking up so you cannot breathe while still in contact?

✅ Before You Answer

• Be sure you distinguish between painful but still voluntary control and involuntary muscle/respiratory paralysis • Check whether the option describes a minimum threshold for respiratory paralysis, not a typical dangerous or fatal shock level • Compare the choices to the known ranges for perception (1–5 mA) and "can’t let go" (around 10–20 mA) and see which is the next step up tied to breathing paralysis
