200mV

200mV refers to a voltage measurement of two hundred millivolts. Voltage is the electric potential difference between two points, and it is measured in volts (V). A millivolt (mV) is one-thousandth of a volt, so 200mV is equivalent to 0.2V. This is a relatively small voltage, commonly encountered in electronic circuits and biological systems.

In electronics, millivolt-level signals are often used for low-power applications or as intermediary signals within more complex circuits. For example, some sensors produce output voltages in the millivolt range. Amplifiers are frequently used to increase these small signals to a usable level for further processing or display. The precise value of 200mV can be significant in sensitive circuits where even small voltage fluctuations can affect performance.

Within the human body, nerve impulses and muscle activity generate electrical signals that are also measured in millivolts. The resting potential of a typical cell membrane, for instance, is around -70mV, and the depolarization during an action potential can reach positive values, often in the tens of millivolts. Therefore, 200mV represents a voltage level that is both practical in electronic design and relevant to biological phenomena.
