Norton’s theorem is a circuit analysis technique which is used to reduce complex electrical circuits to a single current source and one parallel resistor. Statement of Norton theorem: Any linear bilateral network can be reduced to a simple circuit containing one current source and one shunt resistor Given below are steps for Norton’s Theorem Replace … Read more
Y (Wye or Tee) and Delta or (PI) configurations are two special configurations in which electronic components can be arranged. Many times it is important to convert a Wye configuration to delta and vice-versa. Given below is the formula to convert three resistors in Wye configuration to Delta. An example Let’s consider a Wye circuit … Read more
