- a 10 kiloohms resistor is connected in parallel with an inductor L. The parallel combination is then connected in series with a 2 kiloohms resistor and 5nF capacitor. If the whole combination is connected to a voltage supply of 50cis0 volts at a frequency of w=50,000rad/s, find the value of L such that the total current is in phase with the supply voltage.
