### The series of alternating current

1.10 Purely Series Barriers10/02 Series Inductive ObstaclesAn inductor coil has a self inductance L coupled alternating voltage V, then the resulting emf induction coil ujung2Barriers have inductive XL price:XL = inductive resistance (Ohm)

3.10 Barriers Series CapacitanceA capacitor with capacity C connected alternating voltage V, then the capacitor becomes charged, so that at plat2nya have a potential difference ofLarge capacitive barrier XC:

Strong currents which flow in this circuit are:

10.7 Series ResonanceIf the RLC series circuit then XL = XCEffective flow in the circuit will achieve the greatest price that is atIt said circuit in a state of resonance. In this case appliesSo the resonant frequency is

• The relationship between the maximum and effective priceVef = effective voltage (V) Vm = maximum voltage (V) ief = effective current (A) im = maximum current (A)The relationship between price and average maximumVr = average voltage (V) Vm = maximum voltage (V) ir = average current (A) im = maximum current (A)

10.8 Power Flow Back and forthFormulated in direct current power P = VI, with V and i the price is always fixed.But for alternating current electric power is expressed as: multiplication of voltages, currents and power factor.

By:P = electrical power back and forth (Watt)V = effective voltage (V)i = effective strong currents (A)Z = impedance circuit (Ohm)Cos θ = power factor =

Example:Jala2 have a different mains voltage 220 V, what is the maximum voltage value?In a series RLC circuit with R = 80 Ohm, XL = 100 Ohm, and XC = 40 Ohm, connected by alternating voltage source having a maximum voltage of 120 V. Determine the maximum current in the circuit.At frequency of 100 Hz, the reactance of a capacitor is 4000 ohms and reactance of an inductor is 1000 Ohm. If the capacitors and inductors were mounted on a circuit, the resonance occurs at what frequency?In a series RLC circuit with R = 40 Ohm, XL = 50 Ohm, and XC = 20 Ohm, connected by alternating voltage source having an effective voltage of 110 V. Determine the power used by the entire circuit.
