What else can I help you with?
For an eletric current to flow the only thing needed is for two objects to have a difference in charge?
Yes. However, depending on the size and shape of the objects, the amount of current that flows may be small and/or flow for only a brief time until the charges are neutralized. But - if the objects are connected to an electrical power source such as a battery or a wall plug, the charges are continuously supplied and the current continues to flow.
What elements allow electricity to pass through?
Note that "electricity" doesn't flow, only current does, which is one aspect of electricity, does. Current is the flow of electrons.A circuit lets electricity flow through it.Conductors allow the easy flow of electrons. Conductors are metal, usually copper or aluminum.Note that "electricity" doesn't flow, only current does, which is one aspect of electricity, does. Current is the flow of electrons.Metals are good conductors. They provide little opposition (resistance) to the flow of currentNote that "electricity" doesn't flow, only current does, which is one aspect of electricity, does. Current is the flow of electrons.A conductor lets electrons easily flow in it.
Why are two wires used to allow electric current to flow instead of a single one?
Because the current must always travel in a complete loop, going through the circuit and returning to the supply. A current can't travel along only one wire so no power would get to the circuit unless it has two wires.
What happens to an electric current when a circuit is closed?
When a circuit is closed, meaning there is a complete path for the electric current to flow, the current will flow from the positive terminal of the voltage source through the circuit components and back to the negative terminal. This flow of current allows electrical energy to be transferred and work to be done in the circuit.
Something that will not let electricity flow through it is a?
Note that "electricity" doesn't flow, only current does, which is one aspect of electricity, does. Current is the flow of electrons. Bad conductor of current, or an insulator.
An electrical current will always flow?
An electrical current will only flow in a closed loop or circuit where there is a complete path for the electricity to follow. If there is a break in the circuit or an open switch, the current will not flow.
What is a circuit that only has one loop of wire?
A simple circuit that has only one loop of wire is a series circuit. In a series circuit, the components are connected in a single path, forming a closed loop for the current to flow through. If one component fails, the entire circuit will be broken.
When a conductor is moved in a magnetic field a voltage will be induced on the conductor. However current won't flow through the conductor unless the conductor is?
moving
How many paths through which charge can flow be shown in a circuit diagram of a series circuit?
In a series circuit, there is only one path for the flow of charge. The components are connected end-to-end, creating a single, continuous loop for the current to travel through.
How many pathway does a series circuit have?
A series circuit has only one pathway for electric current to flow. This means that all parts of the circuit are connected in a single loop, so the current passes through each component in sequence.
What must occur to electric current?
transfer/movement of electrons
Is there actually current flowing through the return wire?
Yes, there is a current flow through he return wire in a closed circuit. The only time there is no current flow through the return wire is when the circuit is open.
Which circuit element(s) are known as diodes and only allow current to flow through them in one direction?
Diodes are the circuit elements that only allow current to flow through them in one direction.

Something that will not let electricity flow through it?
Something that does not allow current to flow is called an insulator. "Electricity" doesn't flow, only current, which is one aspect of electricity, does. Note, current is the flow of electrons.
