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.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.


What is two or more electrical components connected together called?

Two or more electrical components connected together is called a circuit. Depending on how components are connected, it is either an open circuit, closed circuit, or a short circuit.


What is open circuit and short circuit?

Consider two points (A and B) in an electric circuit. An open circuit between A and B means there is no electrical connection between A and B. A short circuit between A and B means there is an electrical connection between A and B.


What is short circuit ratio of an alternator?

Short circuit ratio is the ratio of field current required for the rated voltage at open circuit to the field current required for the rated armature current at short circuit


What happens when closing and breaking an inductive circuit?

When you close an inductive circuit, since an inductor resists a change in current, the initial reaction of the load is to look like a high resistance. As current builds, the resistance falls. With a theoretical source and inductor, current would eventually reach infinity, that is after infinite time, but practical sources and inductors will reach a plateau current. When you open an inductive circuit, again, since an inductor resists a change in current, the inductor attempts to maintain that current, but there is no conductivity for that current so, the inductor presents a high voltage spike in the reverse direction it was initially "charged" with. With a theoretical inductor, and theoretical infinite impedance, the voltage spike would be infinite. Again, practical inductors have a maximum voltage spike, but this spike can still be quite high, even thousands of volts, which can damage the circuit, so it is important to maintain a conduction path for the collapsing field, often a diode, or a resistor/capacitor filter.

What is a circuit with no load?

An open circuit or a short-circuit (if that circuit is complete).


What is the difference in an open circuit and a short circuit?

an open circuit is a circuit that does not complete the circle. an open circuit does not do the job as the electricity stands still a short circuit is a circuit that wires have crossed and the electricity takes the shortest path. and does not complete all of the points on the circuit


What is the type of circuit called when it has an conductor a switch a electric cell a resistor?

it is called a circuit and when it is closed is called a closed circuit and when open circuit it is called an open circuit


Does an inductive load affects the dc power supply?

Inductor acts like a open circuit to DC at t=0 i.e at instant of closing the switch. Because it does not allow sudden change in current. Refer v= L di/dt. As t-> infinity, inductor acts like a short circuit(if pure).


Why is an open circuit called open?

An open circuit is called open because the circuit has an opening, a disconnection. In other words, there is an open space in the circuit in which the electrons cannot move through.

Two or more electrical components connected together is called a circuit. Depending on how components are connected, it is either an open circuit, closed circuit, or a short circuit.


What is more dangerous a short circuit or an open circuit?

Open circuit Because, if there's an open, there could be machinery still running, or voltage still present. Short shuts a cct down.


What is the design value of short circuit ration of generator?

short circuit ratio is the ratio of field current to open short circuit voltage n the open circuit current. its value for thermal is less than hydro type.


What is a break in an electrical circuit called?

A break in an electric circuit is called an open circuit. Electric current will not flow through an open circuit.


What is open circuit and short circuit?

Consider two points (A and B) in an electric circuit. An open circuit between A and B means there is no electrical connection between A and B. A short circuit between A and B means there is an electrical connection between A and B.


Open circuit and short circuit test?

Open circuit means the circuit is not continuous . A short circuit is continuous but has a fault connecting between either live to neutral or earth .As result of this we saw that this answer is unsufficent to explain short and open circuit on the other hand you can use this answer also like i did:)
