Biasing or applying bias means applying a steady dc voltage. Usually, when we apply a voltage across components like resistors, inductors, capacitors, etc. we do not need to consider the polarity of the voltage applied. But in the case of semiconductor devices such as a diode, BJT, FET, etc., the polarity of the voltage is … Read more
Current transformer and Potential transformer are the types of instrument transformer. An instrument transformer is a special type of transformer that is used in the measurement of high voltage and high current, not allowing measuring instruments to come in direct contact with high voltage circuits. Potential transformer is also known as voltage transformer. In this … Read more
