A circuit must have three basic components to make electricity flow.
1. Source of power or electricity.
2. Wires, switches and conductors through which the current can flow.
3. And finally a load to complete the circuit.

∙ 14y agoYou need a whole circuit. This could be a simple circuit like a piece of wire going from one terminal of a battery to another, or a more complex circuit where the wire would have a switch in it, or an even more complex one where there would be a bulb in the circuit as well. The switch would need to be closed for the current to 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.
Which instrument do you use to measure the flow of current in a circuit?
To measure current you will need an ammeter.
What is current density?
Current density is the amount of electrical current flowing in a unit of cross sectional area of that conductor. You'd look at the current flowing and the cross sectional area of the conductor and make a calculation from that. All you need do is decide on what unit of cross sectional area you wish to use. In wire, we usually use mils. Use the links below for more information.Density current is the measure of the density of flow of a conserved charge
Do you need to apply a load to see a voltage drop across a resistor?
You'll see a voltage drop across a resistor if current is flowing through it. It only has to be a part of a complete circuit, i.e. one in which current is flowing.
Why poiseuille equation not applied to turbulent flow?
Coz poiseuille eq is for poiseuille flow, which is a laminar flow, not turbulent flow. And it also need to be a fully developed , pressure driven flow.
What do you need to complete before the current?
You need a closed circuit. You also need a voltage source.
What do you need to complete before the current flows?
You need a closed circuit. You also need a voltage source.

Does current need free electrons for it to flow?
yes it need ion to flow
What are the parts of an electrical current?
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.
If any men hang to live conductor then will he experience shock?
You would not get shocked because you need to complete the circuit to allow current to flow. If you leaned a ladder against a transmission line you would get shocked because there is now a path for current to flow to ground.
Which instrument do you use to measure the flow of current in a circuit?
To measure current you will need an ammeter.
What are two things required to make electric current flow in a circuit?
you need an electrical supply and a load. nice and simple.
What does an electric current need in order to flow?
negative charge
Why DC supply is need in thyrister?
because thyrister doesn't allow the current to flow unless there is a current flow into the gate. this current must be dc, and the rating of this current depends on the type of thyrister.
What are the disadvantages of insulators?
One disadvantage of a insulator is that it will not let current flow if you need it to. By the same token one advantage of an insulator is that it will not let current flow if it tries to.
What do you need to have a flow of current?
Potential difference. Like the plus and minus on batteries...
