To establish an electric current, there are two requirements that must be met. There must be a closed conducting path that goes from the positive terminal to the negative terminal. The second requirement is to have an electric circuit for the energy to move a positive test charge against the electric field.

What does an electric current need in order to flow?
negative charge
In order for the electrons to move they need a closed losed loop called?
A "circuit".
How do you get a series circuit to work?
In order to work, all the connections must be in order. You also need a voltage source.
What is the purpose of light in a circuit?
None. A circuit does not need a light but in school experiments it is and easy way to see if the circuit is working.
How is the voltage of the power supply for a series circuit calculated?
The circuit by itself doesn't determine the voltage of the power supply. If there's some additional requirement that goes along with the circuit, such as "The current through the circuit must be XYZ amperes.", or "The voltage across the third component from the north end of the circuit shall be ABC volts,", then that requirement would dictate the power supply voltage. But in order to calculate it, you'd need the knowledge of every component in the series circuit.
What is the circuit for reversing an electric motor?
I HAVE A SMALL ELECTRIC CLOCK MOTOR THAT I NEED TO REVERSE. WHAT IS THE CIRCUIT I NEED TO REVERSE IT?
Why does an electric circuit that operates correctly need to be closed circuit?
In order to have the electricity or the flow or electrons going around the circuit, the circuit must be closed. If it is not closed then electrons cannot flow.
What do you need for an electric circuit to work?
1
Does an electric circuit have a beaker?
Electric circuit need a main circuit breaker that can protect the whole circuit from short circuit even in ground fault. It's safer if you use breaker with built in ground protection.
What do you need to form an electric circuit?
Only a power source and a conducting path between its terminals. If you need the circuit to accomplish anything useful, then there's typically some sort of useful device in the conducting path, that uses power from the source to do whatever it is that you need done.
The function of a capacitorin an electric circuit is to?
The function of a capacitor or an electric circuit is to store energy. It keeps this energy stored until it is need for release at a later time.
why do circuits need fuses?
Any electric circuit need to be equipped with electric fuses to protect the electric appliances or any electric/electronic equipment from damage due to unexpected electric current sudden or transient increase.
What is essential to make a circuit?
In order to make a circuit, you need a power pack, connecting wires (2 or more) and a load. The load can be something like a lightbulb or any form of a resistor.
What is the role of reactive power in an electric circuit?
Some electrical machines work on the principle of electromagnetic induction. For such events to occur, we need inductor due to which reactive power flows in the circuit. Since, this power is due to the energy storing elements in the circuit like inductor and capacitor. That is why, we need reactive power in a electric circuit.
How can you draw electric circuit in Microsoft Word?
It's very easy to draw an electric circuit in Microsoft Word. You just need to open up the graphics menu from the top, and you'll get access to the drawing tools for circuit drawing.
You need a cell in the circuit because?
Assuming you are talking about electrical circuits: "Cell" is the name given for a battery. Without a cell in the circuit, there is no supply of electricity. Therefore there is no electric circuit.
What do fuses do?
Structure and use of a fuse: A fuse contains of a metal contact cap,glass casing,thin metal wire with a low melting point.When the electric appliances is faluty,the excess electric current will flow through the crcuit.Owing to the heating effect of elecric current,a large amount of heat will be produced.The circuit may thus occured a fire.The installation of fuse can stop excessive electric current.the low melting point thin wire in the fuse will melt and break the circuit in order to protect the electric appliances and prevent a fire.But fuse is quite unconvenient that after it's bruned out,you need to replace a new one. fuse rating: fuse rating refers to the amount of electric current that can flow through the fuse without melting the thin metal wire.The higher rating can provide larger electric current.We should choose a greater ampere fuse than the electric appliances in order to prevent the breaking of circuit when electric appliances are working normally. The similar appliances:Circuit Breaker The use of a circuit breaker is similar to a fuse.When an electric current increases suddening and exceeds the circuit breaker's raging,the circuit breaker will turn to"OFF" switch automatically and break the circuit in order to protect the electric appliances and prevent a fire.It's more convenient than a fuse cause you only need to turn to"ON"switch when reconnected.
