What else can I help you with?
When electric circuit is closed no current flow through it IS the statement is correct?
yes... this is possible if a diode i connected in reverse bias with a battery and a resistor for example. A diode in reverse bias means its anode will be connected to positive terminal of the battery and its cathode to the negative terminal of the battery. In such a case, minimal current flows through the circuit which can be neglected.
What is a closed circuit?
A closed circuit is a kind of electric circuit in which the path that the electrons follow forms a complete circuit.
What can be used to produce a continuous flow of charge?
A battery will do this, when connected to a closed circuit (for a while).
What direction does electricity flow in a simple circuit?
This is a very complicated question in reality. in a simple Dc circuit (i.e. a battery driven circuit) there are 2 way's that current is talked about. the reason is historic, so here goes a very brief answer. When people first beagn to identify how current flowed in circuits there was a school of thought that a sort of liquid flowed in electric circuits, and the driver (battery) had parts that had an excess of the liquid, and parts that had less. The bits with more were positive + and the bits with less were lacking (negative) - Naturally the liquid would try to balance the circuit, and so current was said to flow from positive to neagtive. This is referred to as conventional current. so Conventional current is said to flow from positive to negative. Thanks to the work of Earnest Rutherford and Niels Bohr (a student of rutherford) we now know that electric current flows as a result of electrons in the wire bumping along the wire jumping from atom to atom. This actually means that in reality current should have been flowing from negative (a surplus store of electrons) to positive (a lack of electrons) to avoid confusion, a new term was coined. Electron Flow. so Electron Flow is from Negative to Positive. Now to your question. How does electricity flow in a simple circuit. A Battery has 2 plates, one charged with a surplus of electrons, and one lacking electrons. When a circuit is closed, the difference in the potential of the plates (called potential difference, and measured in Volts) causes electrons to be pushed into one end of the wire at the negative terminal, while a strong pull is made on the other end of the wire by the positive terminal. The electron at the negative terminal pushes its way onto the copper atom, making it's charge unbalance, so it lets one of its electrons go, this free electron, moves on the next atom ... and so on, literally bumping electrons along the wire in the direction of pull, created by the battery. finally an electron exists the wire into the battery and one electron has been transfered to balance the battery charge. The stronger the force (Voltage) the faster the electrons flow, this continues until the driving force (battery) is balanced (discharged) when we say the battery is flat. Hope this makes it a bit easier to understand what is happening, even if I can't exactly answer the question But I suspect your answer should be Electron Flow in a simple electrical circuit is from Negative to positive.
How does closed circuit work?
A closed circuit works by having electricity flow in a complete circuit or circle or any closed shape.
Does a complete circuit have closed and electric current flows?
Yes, a complete circuit has a closed loop for the electric current to flow. A closed circuit allows the flow of electrons from the negative terminal of the battery to the positive terminal, completing the circuit and powering the devices connected.
Desctibe what happens to the negative charges in a simple circut when the switch is close?
When the switch is closed in a simple circuit, the negative charges (electrons) flow from the negative terminal of the battery through the circuit and back to the positive terminal. This flow of electrons creates an electric current that powers the circuit components.
What part of the curcuit pushes the electrons?
The voltage source (such as a battery) is what provides the energy needed to push the electrons through the circuit. Electrons flow from the negative terminal (cathode) to the positive terminal (anode) of the voltage source in a closed circuit.
A closed path through which electrons can flow is?
An electrical circuit is a closed loop through which electrons can flow. It typically consists of a power source (such as a battery), conductive wires, and components like resistors and lightbulbs that use the flow of electrons to perform various functions.
Why does the flow from the battery increase when the switch is closed?
When the switch is closed, it creates a complete circuit for the flow of electricity from the battery. This allows the electrons to move freely and increases the flow of current in the circuit.
What is the evidence that an electrical circuit is closed?
When that circuit has no breaks. It is an endless path of current flow.
Why is there a positive and a negative in a car battery?
Because you won't get a complete and closed circuit without a ground.
What does an electric current need in order to flow?
An electric current needs a closed circuit, which provides a complete path for the flow of electrons. This circuit typically includes a power source, such as a battery or generator, connecting wires, and a load, such as a light bulb or motor, that utilizes the electricity. Without a closed circuit, electrons cannot flow continuously and no electric current is generated.
In order for the electrons to move they need a closed losed loop called?
In order for electrons to move, they need a closed loop called a circuit. A circuit allows electrons to flow from the negative terminal of a voltage source, through the electronic components, and back to the positive terminal, enabling the operation of devices.
Why are there two terminals in a battery?
A battery has two terminals—positive and negative—because they facilitate the flow of electric current. The positive terminal, often marked with a "+" sign, attracts electrons, while the negative terminal, marked with a "-", releases them. This difference in charge creates an electric potential difference, allowing electrons to flow from the negative terminal to the positive terminal when the circuit is closed, thus providing electrical energy for devices.
How does electricity flow through a circuit?
Electricity flows through a circuit when a power source, like a battery, creates a voltage difference that pushes electrons through a closed loop of conductive materials, such as wires. The electrons move from the negative terminal of the power source, through the circuit components, and back to the positive terminal, creating a continuous flow of electrical current.
What supplies the electrons that will flow through the circuit?
The metals making up the circuit contain electrons themselves, and when they are together they form a conduction band (a 'sea' of delocalised electrons moving freely around positive atomic kernels) between the bonded metals. So no electrons are actually 'poured in', they are just pushed around.
