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

∙ 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.
Is a switch needed to make a circuit work?
Yes, a switch is needed to control the flow of electricity in a circuit. It allows you to open or close the circuit, which determines whether the electrical current can flow through it or not. Without a switch, the circuit would be always on and the device connected to it would not be able to be turned off.
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.
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 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.
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.
Are wires and a light bulb needed to make current flow?
Yes, wires are needed to create a closed circuit for current to flow. A light bulb can serve as a load in the circuit, converting electrical energy into light and heat.
Why must a circuit be closed in order for a current to flow?
Current flows in a closed circuit because the circuit provides a complete path for the flow of electric charge. If a circuit is open, there is a discontinuity in the path, preventing the flow of current as there is no complete loop for the charge to travel through.
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.
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 circuit with two or more branches for current to flow called?
Parallel circuit
When a switch is closed in an electrical circuit do electrons flow through the conductor?
Yes, when a switch is closed in an electrical circuit, electrons flow through the conductor, providing the electrical current needed for the circuit to work. The flow of electrons is what generates electricity and powers the various components in the circuit.
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:)
