What is the functioning of choke coil?
A choke coil is used in several electrical devices. The function it has is to block AC currents from passing through as it allows DC currents to pass through.
How do you measure the current through a circuit without intercepting the supply?
Add an ammeter in parralel with the circuit. An ammeter in parallel with a circuit to be measured will not measure any current. In fact, placing an ammeter in parallel will cause a short. The ammeter must be placed in series with the circuit to be measured. It should be noted that this technique only allows for small magnitudes of current to be measured. One should not try to measure more than 10 amps using this method. However, this is not the goal of the question asked. I am not 100% sure what "intercepting the supply" means but I think the person asking the question means without breaking the circuit? In this case one could use a clamp on ammeter. There are several varieties that can measure low currents and there are those that can measure 100s of amps.
Why is current the same in all points of a circuit even with resistors on it?
Electrical current (amperes, or coulombs per second) is the flow of electrons from one point to another. In a series circuit, there is only one path for those electrons to flow, so the amount of flow at different points in a series circuit is always the same. That's not to say that the current does not change - certainly different resistance, for instance, would cause different current - the point here is that, for a given set of conditions, the current in a series circuit is the same at every point in the circuit. This is Kirchoff's current law. The signed sum of the currents entering a node must always be equal to zero. If a node consists only of two elements, then the current entering the node from one element must be equal to the current leaving into the other element. Since a series circuit consists only of nodes with two elements connected together, that means the current at every point in a series circuit is the same. Think of this analogy. Connect several water hoses in series with modulating valves between each section. Apply water pressure to one end. Make different adjustments to the valves, representing different resistances. Note that, although the water pressure is different at different points (think voltage), the current flow at different points (think current) is the same.
When circuit that connects several objects in one complete path is called a?
A series circuit or a parallel circuit
Each branch in a parallel circuit may hold several resistors yes or no?
No. What you are describing is a series-parallel circuit, not a parallel circuit.
What is a circuit with several current paths whose total current equals the sum of the currents in its branches?
This is a parallel circuit, each of the parallel current paths draws a certain current, and the input current equals the output current, so the sum of all current through each path has to equal the total current.
How parallel and series circuit different?
In a series circuit, current has to pass through each part of the circuit. In a parallel circuit, the current has several alternative paths.
Is current the same at all points in a circuit?
By Kirchoff's current law, the sum of the signed currents entering a node is zero. In a parallel circuit, this means the sum of the (often single) current(s) entering a node (junction) is the same as the sum of the (two or more) currents leaving that node. To determine the current in a particular branch, you need the voltage and resistance, or you need something else that you can use to calculate the current. In the second case, if you know the total current and one branch current in a two branch circuit, you know the other branch by calculating total minus first branch. For the first case, one method is to take advantage of Kirchoff's voltage law, which states that the signed sums of the voltage drops around a series circuit is zero. In a parallel circuit, this means that the voltage drop across each branch is the same. If you then also know resistance, you know current.
What happens as a current flows through a parallel circuit?
if the circuit is a series circuit (all loads wired in a single line , one after the other ) then the current will be the same in any part of the circuit . if there are several different paths for the current to take , then each path will carry a different percentage of the total current . when each of these different current values are added together , they will equal the total supplied current.
In parallel circuit there are several paths for the current to take?
No. By definition, a parallel circuit occurs when there is more than one alternative path.
What is the functioning of choke coil?
A choke coil is used in several electrical devices. The function it has is to block AC currents from passing through as it allows DC currents to pass through.
What is current chopping?
When low inductive currents, such as magnetiing current of transformer, shunt reactors are interrupted by breaker, there is rapid deionization of contact space and may cause the current to be interrupted before its neutral zero. This phenomena is called current chopping. This generally occurs during opening small inductive currents by vacuum ckt brkr or air blast circuit brkr. The transient voltage having high restriking voltage RRRV appears across the contacts, unless the arc restrikes. If it restrikes a further, chop may occur or several chops may occur before the current is finally interrupted. Circuit breaker may fail to clear the current. Circuit breaker in which dielectric strength of contact space grow at slow rat, the problem of current chopping is less severe as the gap breaks down and absorbs successive magnetic energy by restriking. Oil circuit breakers are therefore suitable to such application. This is the reason that sometimes in air blast circuit breakers resistance switching is adopted.
What can interrupt the flow of an electric current?
Several factors can interrupt the flow of an electric current, including a break in the circuit, a faulty component, overheating, or a power surge. These interruptions can cause a loss of power or damage to devices connected to the circuit.
How LED flashing circuit board function?
It may work in several different ways, depending on the actual circuit used. As asked no better answer can be given than the circuit board alternately turns the current in the LED on and off.

I can give you several sentences.The currents in this area are dangerous.The river's currents will float you gently down to the campground.If you can find the right air currents, the balloon can travel for hundreds of miles.
A device that protects a circuit from current overload is called?
Fuses or circuit breakers are termed 'overcurrent protection devices', which protect circuits from either an overload current or a short-circuit current.
