Question

Why is kirchoff's law not applicable to ac current

Answer 1

it is applicable to ac current :P

Answer 2

its not applicable only when you have an inductor in the circuit.. or in general you have a CHANGING magnetic field.. in that case you go for faraday's law..!!

Answer 3

AC Produces Variable Voltage

Answer 4

I think we can well use the ac circuit for resistances, but when phasor concept is to be used the algebraic rules does not hold good

Answer 5

Excuse me but Kirchoff's Rules do apply to AC circuits. Check any circuit analysis text. You must use Phasors or Sinors in the equations.

Answer 6

The Sinor or Phasor formalism is equivalent to a vector formalism and keeps track of the magnitude and phases of the voltages and currents in the circuit. It is actually a complex number representation of the voltages currents and impedances in the circuit.
