BLK Super Speciality Hospital Technical Support Engineer Interview Questions and Answers

Kirchhoff's current law states that the total current entering a junction is equal to the total current leaving the junction.

• Also known as Kirchhoff's first law

• It is based on the principle of conservation of charge

• The sum of currents entering a junction is equal to the sum of currents leaving the junction

• Can be used to analyze complex circuits

Three phase to one phase conversion can be done using a transformer.

• Use a three-phase transformer to convert the voltage to single-phase

• Connect the three-phase transformer in a delta configuration

• Use a single-phase transformer to step down the voltage to the desired level

• Connect the single-phase transformer in a wye configuration

• Use a phase converter to convert the three-phase power to single-phase power
