• The relationship between the maximum and effective price Vef = effective voltage (V) Vm = maximum voltage (V) ief = effective current (A) im = maximum current (A)

The relationship between price and average maximum Vr = 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.
