WebP0138 code definition O2 Sensor Circuit High Voltage (Bank 1, Sensor 2) What the P0138 code means P0138 is the OBD-II generic code indicating the O2 sensor for bank 1 sensor 2 fails to have a lower voltage output below 1.2 volts for more than 10 seconds indicating a lack of oxygen in the exhaust stream. What causes the P0138 code? WebInstrument transformers are widely used to isolate instruments from high-voltage circuits and to measure several electrical parameters, including current, voltage, energy, frequency, and power. It is used with protective circuits to operate circuit breakers and relays to protect power systems. Instrument transformer ensures operators' safety ...

Why does Flow always occur from Higher Potential to Lower Potential?

WebFeb 4, 2015 · You can have a high potential difference (which is what voltage is), and a low current, simply by having a high resistance in place to block that current. Think of it like a water hose turned on full blast, with a hose gun attached to the end. WebOct 16, 2015 · Too high a voltage tends to cause a catastrophic breakdown of a transistor. Once you apply over-voltage stress and the transistor breaks down, the pin will show short circuit (usually to ground). If you catch it, or limit the fault current some how, this type of failure will not be visible outside of the IC. list of federal holiday 2021
