  • How do you solve AC circuit problems?

    The electric current and electric voltage of an alternating current sinusoidally change over time which makes them alternate positive and negative values. Thus, AC circuit equations are written by using the root-mean-square (rms) value which can better describe both I and V as follows: I r m s = I 0 s q r t ( 2 )
  • How do you calculate AC circuits?

    In a purely resistive circuit including an AC RMS power supply, the dissipation of power is the same as compared to a resistor connected to a DC power supply. P = VRMS * IRMS = I^2RMS * R = V^2RMS/R.. In the above equation, both the VRMS and IRMS are RMS values of current & voltage respectively.
