The particles that carry charge around a circuit are electrons. In some semiconductors, missing electrons in a crystalline structure (of silicon or germanium), caused by adding special impurities, form spaces called "holes" where there is a missing electron. These "holes" can also travel but, in the end, it is electrons that move in the opposite direction to fill those holes that carry the current.
What else can I help you with?
How can you start and stop electric circuit?
You can start an electric circuit by closing the circuit, typically by turning a switch on. You can stop an electric circuit by opening the circuit, usually by turning a switch off or disconnecting a wire.
What is the space around a charged object where electric forces act?
The space around a charged object where electric forces act is known as the electric field. This electric field exerts a force on any other charged particles that are placed within it, causing them to experience an electric force.
Why must a circuit be closed in order for a current to flow?
A circuit must be closed in order for a current to flow because it helps keep a current flow pass. When the switch is closed on a circuit there is a constant flow. When the switches open the flow is disturbed around the circuit.
When is current produced?
Electric current is produced when there is a flow of electric charge in a circuit. This flow of charge is typically generated by a voltage source, such as a battery or power supply, which creates a potential difference that pushes the electrical charge around the circuit.
What is the flow of electrons around a circuit?
In a circuit, electrons flow from the negative terminal of the power source (e.g., battery) through the conductive wires and components, such as resistors and light bulbs, back to the positive terminal. This flow creates an electric current that powers the devices connected in the circuit.
What does the electric battery do?
If there is a full circuit, it will send current around it.
What happened when Volta connected the parts of his cells in circuit?
An electric current flowed around the circuit.
How can you start and stop electric circuit?
You can start an electric circuit by closing the circuit, typically by turning a switch on. You can stop an electric circuit by opening the circuit, usually by turning a switch off or disconnecting a wire.
Which part of the atom moves around the circuit carrying energy?
The part of the atom that moves around the circuit carrying energy is the electron. Electrons are negatively charged particles that can flow through conductive materials, such as metals, when a voltage is applied. Their movement creates an electric current, which is the flow of electrical energy through the circuit.
What is happening when you turn an electric circuit off?
When you switch off an electrical circuit you tend to create a 'break' in the circuit, preventing the electric current to flow around the circuit, this can be caused by a simple switch or a break in the circuit, e.g a disconnected wire.
Can 2 cells push electric current harder round a circuit?
No, cells do not push electric current harder around a circuit. Electric current is driven by the voltage difference between the cells. Adding more cells in series increases the voltage, which can result in more current flowing through the circuit, but the cells themselves do not push the current harder.
Is electric current stored anywhere?
Electric current is the movement of charge around a circuit and so cannot really be stored, however, the energy which it carries is stored in most things.
A wire wrapped around a magnet is an example of a open circuit?
No, a wire wrapped around a magnet is an example of a closed circuit, as the wire forms a continuous loop for the flow of electric current. An open circuit is a circuit that is interrupted, preventing the flow of current.
What is the space around a charged object where electric forces act?
The space around a charged object where electric forces act is known as the electric field. This electric field exerts a force on any other charged particles that are placed within it, causing them to experience an electric force.
Why must a circuit be closed in order for a current to flow?
A circuit must be closed in order for a current to flow because it helps keep a current flow pass. When the switch is closed on a circuit there is a constant flow. When the switches open the flow is disturbed around the circuit.
What does a current do in a circuit?
goes around the circuit carrying electricity all around the circuit
How current electricity moves in a circuit?
You need a source of electrical potential difference, also known as voltage (which is the technical term for what for you call "electric pressure"). The easiest and most common voltage source is a household battery. Hook up the positive electrode of the battery using a conductor (eg. a copper wire) to one end of your circuit and the negative electrode to the other end, and voila, you'll have electric current flowing through your circuit.
