Question

find the phase difference between voltage and current in series lcr circuit at half power frequency​

Answer 1

Answer:

There is no answer to your question. L causes Xl a form of resistance to AC that makes current lag behind the voltage by 90 deg. C causes Xc a form of resistance that makes the current lead the voltage by 90 deg.. The lead, Lag is a form of time, where 360 degree is equal to 1/60 of a second when frequency is 60 HZ. Both Xl and Xc are affected by the frequency and their affects are direct opposites. The combination of the NET affect of Xc, Xl is combined vectorially with the R in the circuit. The difference between these two form an angle called the phase angle. This angle will represent the actual Lead or Lag in time between the current and Voltage.
