A DC shunt motor is a motor using DC supply with the the inductor connected parallel to the armature.
An inductor is a magnetic device that resists a change in current. It is constructed with windings that can be backed by ferro-magnetic cores. The equation of an inductor is ... di/dt = V/L ... meaning that the rate of change of current per time is proportional to voltage and inversely proportional to inductance. Inductors, since they work on magnetic fields, can be coupled, as transformers, motors, and generators. A capacitor is a charge device that resists a change in voltage. It is constructed with parallel plates. The equation of a capacitor is ... dv/dt = I/C ... meaning that the rate of change of voltage per time is proportional to current and inversely proportional to capacitance. Inductors and capacitors, since they work in opposite phasor angles, can be coupled to make resonant filters, giving bandpass or bandcut to particular frequencies.
No. You have to consider the inductor and the capacitor. Impedance of RLC circuit is equal to to the Value of Resistor Only AND Only on Resonate frequency. otherwise u have to cnsider resistance inductance and capacitance together in series.
When a resistor and an inductor are both connected to an AC supply, the current in the resistor is in phase with the voltage, while the current in the inductor is a quarter-cycle (90 degrees) behind. Supposing they both draw 1 amp on a 12-volt AC supply. The resistor will dissipate 12 watts, while the inductor will dissipate no power. Any power that enters the inductor comes back to the generator in a later part of the cycle. But the current drawn from the supply is 1.414 amps, so this would be a load with a power factor of 0.707.
When they are in parallel the same voltage appear across both. The resistor carries a current of V/R, the inductor carries a current of V/(jwL). So the current in the inductor is 90 degrees behind in its phase.
Inductance in parallel is the reciprocal of the sum of the reciprocals of the individual inductance's. LPARALLEL = 1 / SummationI=1toN (1 / LI)
Inductors in Series - L total = L1 + L2 +L3. Inductors in Parallel - 1/Lt = 1/L1 + 1/L2 + 1/L3 Resistors in Parallel - 1/R total = 1/R1 + 1/R2 + 1/R3 Resistors in Series - R total = R1 + R2 + R3

A:The inductor does not allow ac signal to pass through. It blocks ac and passes dc. If the switch is open, then the ac signal wont pass. If the switch is closed, then the ac signal will pass through the switch.AnswerIt is incorrect to say that an inductor 'does not allow' the passage of an alternating current. An a.c. current will pass through an inductor, although the inductor will limit the value of that current due to the inductor's inductive reactance. Inductive reactance, which is expressed in ohms, is directly-proportional to the inductance of the inductor and to the frequency of the supply. The value of the current is determined by dividing the supply voltage by the inductive reactance of the inductor.If the switch is connected in parallel with the inductor, then closing the switch will apply a direct short circuit across the inductor, and the resulting short-circuit current will cause the circuit's protective device (fuse or circuit breaker) to operate.
Because it is simple phenomenon of electricity everything(resistance,capacitor,inductor) connected in parallel holds the same voltage across the each parallel element.

A resonator is a circuit that responds to a narrow range of frequencies. A typical resonator is a tuned circuit containing an inductor and a capacitor in series or parallel. A series connected tuned circuit has zero impedance at the resonant frequency, while a parallel tuned circuit has infinite impedance at the resonant frequency. The resonant frequency in both cases depends on the inductance times the capacitance: F = 1 / (2.pi.sqrt(LC)) If the inductance is in Henrys and the capacitance in Farads, the answer is in Hz.
When an inductor is suddenly connected in parallel with a charged capacitor, the current through the inductor and the voltage between its ends will oscillate at the frequency of F = 1 / 2 pi sqrt(L x C) . With real-world components, having resistance and connected through wire that has resistance, the amplitude of the oscillation will steadily decrease as energy is lost in the circuit, and the oscillation will eventually become too small to measure, and disappear.
just like it soundsseries resonant has capacitor & inductor in seriesparallel resonant has capacitor & inductor in parallel

the bridge is preferably balanced by capacitor parallel attached resistance value. so, q factor of the inductor is given by w L / C at balance condition. q-value is low prefer
