प्रश्न
Are Kirchhoff’s laws applicable to both AC and DC circuits?
Advertisements
उत्तर
Kirchhoff’s laws are applicable for DC as well as AC circuits. They can be accurately used for DC circuits and low-frequency AC circuits. In the case of AC though, summation of current should be done in vector form or using the instantaneous value for the AC components of the circuit.
