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

∙ 9y ago
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

∙ 9y agoThe two things needed to make current flow in a circuit are no. 1 there must be a source of electromotive force (EMF) and no.2 there must be a complete path for current..

Why must a circuit be closed in order for current to a 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.
In a circuit the purpose of a switch is to?
In a circuit, the purpose of a switch is to control the current flow to the load by opening the circuit (off) or closing the circuit (on). When the circuit is open, the is no complete loop through which the current can flow. When the switch closes the circuit, it restores the loop, and thus allows the current to flow.
How do you build a circuit?
Three main components that are needed to build a circuit will be a power source. This supplies the circuit with a voltage to operate. A load to make the current flow through the circuit, and conductors to join these two devices together to carry the current.
How a fuse controls the flow of electric current in a circuit?
A fuse does not control the flow in a circuit, it limits the current in a circuit. If the load in a circuit shorts out the fuse link melts and opens the circuit and stops the current flow and prevents the wires feeding the circuit from melting and catching fire. resist
What happens to an electric current when a circuit is closed?
If the circuit is closed the electric current will be closed as well.
What are to things needed in order for current to flow in a circuit?
voltage and ground
What condition are necessary for a current to be present in a circuit?
The only two things needed for current flow are electromotive force or voltage and a conductor. The amount of current flow will depend on the "Resistance" in the circuit.
What device is needed for current to flow in an electric circuit?
Too vague of a question. As long as it is a closed circuit it will flow.
What is needed for electricity to flow?
current - caused by protons (+) and neutrons (-) flowing around a circuit
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.
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.

The opposition to the flow of electrical current?
In a DC circuit . . . resistance. In an AC circuit . . . impedance.
What does a load do to the flow of electrical current in a series circuit?
A load increases the flow of electrical current in a series circuit. No load, no flow.
What is a closed path through which current can flow?
A closed path through which a current can flow is called a circuit. Electric Circuit:)
What is the name for the status of a circuit that has breaks which electric current that cant flow?
The name for the status of a circuit that has breaks which electric current that can't flow is called a Closed Circuit. Electric current cannot flow through an open circuit.
In a circuit the purpose of a switch is to?
In a circuit, the purpose of a switch is to control the current flow to the load by opening the circuit (off) or closing the circuit (on). When the circuit is open, the is no complete loop through which the current can flow. When the switch closes the circuit, it restores the loop, and thus allows the current to flow.
