The four elements of a complete (electrical) circuit: 1)A source of input (power supply) 2)A means of conductivity (usually wire) 3)A means by which to open and close the circuit (a switch) 4)An output device (motor, light bulb, etc)

What are two things required to make electric current flow in a circuit?

you need an electrical supply and a load. nice and simple.


A complete electric circuit includes a voltage source current wires and something to ground the flow of current?

If you ground the flow of current like the last part of your question states you will not have a complete circuit as the circuit will open on a short circuit. To make a complete circuit operate you need a power source, an overload device to protect the conductors of the circuit, conductors to carry the current and a load across the power source which causes the current to flow in the circuit. Leave any one of these things out and you will not have a complete circuit.


Is voltage the force that causes motion?

Voltage is the measure of the electric potential difference between two points in a circuit. It is not the force that causes motion directly, but it provides the potential energy needed to move electric charges through a circuit. The motion of electric charges in a circuit is driven by this potential difference, or voltage.


What 3 things do you need for an electric current?

To have an electric current, you need a source of voltage (such as a battery or power supply), a complete electrical circuit (includes wires and components), and a conductive material (such as copper wire) for electrons to flow through.

What are to things needed in order for current to flow in a circuit?

voltage and ground


What are three things needed for a closed circuit to occur?

For a closed circuit to occur, you need a power source to provide energy, a complete loop or pathway for the current to flow through (including conductive materials and wires), and a load or device that uses the electrical energy flowing in the circuit. This allows the circuit to be continuous and functional.


What two things are needed to make a current flow in a circuit?

For the circuit to be connected all the way round because if there are breaks in the circuit the electricity will not flow back round. and number 2 a battery or a power source because without power where is the electricity coming from to be honest. Hope it helped. Thanks. xx

What are the two things needed to make current flow in electricity?

A flow of electrons is needed to have a current. And there (usually) must be a complete circuit. And you need a voltage to make the current move around your circuit. All tied up in Ohms Law - which I'll leave to you.


What 3 things do you need to have for electric current?

To have electric current, you need a source of electric potential difference (voltage), a closed circuit that allows the flow of charges, and a conductive material through which the electric charges can move.
