If an inductor and a switch are connected in parallel through which the current will flow in an AC circuit?
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.
Answer
It 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.

How does a inductor or capacitor returns power to circuit?
A: Current flow only if there is a return path to the source it does not matter what it is connected to. What leaves at one end of the source will be identical to the return in current
Should a Voltmeter always be connected in a series with a component?
Voltmeter should be connected always in parallel to a circuit ANSWER : IT should be in parallel except when used to measure current. Then it should be placed in series across a shunt.
Why voltage leads current in a inductor?
Eli the ice man. Voltage (E) before Current (I) in a coil (inductor)(L) Current (I) before Voltage (E) in a Cap. (C) Got it?
Why L and C are connected in parallel in a LC filter?
LC are connected in parallel combination to short out signals too high or too low in frequency from getting to the load.FYI:Series LC circuits give minimum impedance at resonance, while parallel LC (“tank”) circuits give maximum impedance at their resonant frequency.The LC circuit behaves as an electronic resonator, which are the key component in many applications. Oscillators Mixers Graphics tablets Filters Electronic article surveillance & TunersFor example: a capacitor/inductor oscillator acts as the tuner for the radio.The sine wave that matches that particular frequency will get amplified by the resonator, and all of the other frequencies will be ignored. In a radio, either the capacitor or the inductor in the resonator is adjustable. This is how you "tune in" different stations on the radio :)In a nutshell: A series resonant circuit provides voltage magnification and a parallel resonant circuit provides current magnification.
Why does one bulb make the others go out in a series circuit?
because current in parellel divides unlike in series if one fails all will failsAnswerThe parallel circuit's load current doesn't 'divide'. It's the other way around! Each branch draws an individual current which then 'combine' to form the circuit's load current. However, the reason that the remaining lamps connected in parallel always work, even if one fails, is because each branch of a parallel circuit is subjected to a common supply voltage.
What is the relationship of current through the resistor and inductor in the LR parallel circuit?
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.
When a parallel LC circuit is tuned to resonance will the current be at a maximum or a minimum?
Inside the circuit loop between the inductor and capacitor the current will be at maximum. Outside the circuit the current through the LC tank circuit will be at minimum. It depends on where you are measuring it.
What is the output when a fully charged capacitor connected parallel to the inductor?
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.
Why is a voltmeter connected in parallel in an electrical circuit?
A voltmeter is connected in parallel in an electrical circuit to measure the voltage across a specific component or part of the circuit without affecting the flow of current through the circuit.
What component limits current in a circuit?
A resistor or an inductor. The inductor limits transient current, not steady state current.
What is the name of a circuit in which the current splits at the junctions?
A parallel circuit is one in which the current splits at the junctions. In a parallel circuit, different components are connected across the same voltage source, allowing for multiple pathways for current to flow.
What is the hypothesis for parallel circuits?
In a parallel circuit, the hypothesis is that when components are connected in parallel, the total current flowing into the junction equals the total current flowing out. Essentially, the hypothesis states that the total current remains constant regardless of the number of parallel paths.
Why is the parallel resonant circuit called an rejector circuit?
THE PARALLEL rlc CIRCUIT IS CALLED A REJECTOR CIRCUIT BECAUSE IT REJECTS DOWN THE CURRENT. THE REASON IS AT RESONANCE THE IMPEDENCE OF THE CAPACITOR BECOMES EQUAL TO THAT OF THE INDUCTOR SO NO CURRENT FLOWS. AT LOW FREQUENCY THE CAPACITIVE REACTANCE IS LOW SO ALL THE CURRENT FLOWS THROUGH THE INDUCTOR AND WHEN THE FREQUENCY IS HIGH ALL THE CURRENT WILL FLOW THROUGH THE CAPACITOR BECAUSE AT THAT POINT THE REACTANCE OF THE CAPACITOR IS LOW. SO WE OBTAIN A V-SHAPED GRAPH WITH THE PEAK OF V INDICATING THE REJECTION OF CURRENT.
If I have a circuit with four lamps each lamp is individually connected across the circuit so that the same current is not flowing through each lamp What type of circuit is this?
Parallel Parallel
What are the differences between a series and parallel circuit when connecting batteries?
In a series circuit, batteries are connected end-to-end, increasing the total voltage but keeping the same current. In a parallel circuit, batteries are connected side-by-side, keeping the same voltage but increasing the total current.
What type of an electrical circuit has more than one current branch?
A parallel circuit has more than one current branch. In a parallel circuit, the components are connected in separate paths to the voltage source, allowing for multiple current paths and different current levels through each branch.
How is a series circuit different to a parell circuit?
The difference between a series and parallel circuit is that a series circuit is connected in such a way that the same current intensity flows through the elements while a parallel circuit is connected in such a way that the same potential appears across their terminals.
