Determine ZT for the circuit if inductive reactive is 10220 and resistance is 9850. Answer:

An inductive coil of resistance 15 ohms and inductance 0.2 is commented in parallel with a 100 microfarad capacitor to a variable frequency supply.Find the frequency at which the total current taken is in phase with the supply voltage. What is the value of this current if the voltage is 200V.Draw a phasor diagram

In alternating current, AC, theory, the voltage through an inductor leads the current by a phase angle of 90°. Complex numbers can help in this situation as when a real number is multiplied by i it rotates through 90° on the Argand diagram, with the magnitude remaining the same. This allows us to specify the impedance through an inductor as a complex number. This can be combined with a resistor to give a combined impedance of z = r + Li. If we have two such elements in a circuit, we can use complex numbers to determine the total impedance when they are in series and in parallel. In series Zt = Z1 + Z2 In Parallel
