At first R = 10 ohms, L = 20mH and frequency of 1000rad / s, the current measured is 2.2361A at 89.44 leading power factor. A) Determine the initial capacitance. B) However, a fault occurs on the capacitor branch making its capacitance 20% lower and a resistance of 5 ohms is detected. If this faulty circuit is rerun but at a frequency of 500 rad / s, determine the new current that will flow through the circuit.arrow_forward
- Please answer quickly "In a R-L series circuit, applied voltage is in phase with the total current." True False "In series-connected ac circuit, the total voltage across the circuit and the voltage across each elements are the same."
