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
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.
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.
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.
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.
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
voltage and ground
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.
Too vague of a question. As long as it is a closed circuit it will flow.
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.
No, not at all, current can flow between any two opposite poles. Usually a power source and wire are used, but current flows through lightning and such.

In a DC circuit . . . resistance. In an AC circuit . . . impedance.
A resistor restricts the flow of current in an electrical circuit by resisting the flow of electrons. This causes a decrease in the amount of current that can pass through the circuit.
A load increases the flow of electrical current in a series circuit. No load, no flow.
Parallel circuit
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.
