To have an electric current, you need a closed circuit that allows the flow of charged particles, such as electrons. This circuit typically includes a source of electrical energy, like a battery or generator, conductive materials (wires), and a load (such as a light bulb or motor) that uses the electrical energy.
What else can I help you with?
What provides an electric current in an electromagnet to generate magnetic fields?
An electric current flowing through a coil of wire provides the energy needed to create magnetic fields in an electromagnet.
What is the opposite of a electric current?
The opposite of an electric current is the absence of an electric current, meaning no flow of electric charge through a conductor.
Is The units of electric current is the volt?
NO! (the units of electric current is Amperes).
What is is the dimensional formula of electric current?
The dimensional formula of electric current is [I] = [A], where I represents current and A represents ampere.
What is the relationship between the electric field and current in a circuit?
The electric field in a circuit is directly related to the current flowing through it. The electric field is what drives the flow of electric charge, which is the current. In other words, the presence of an electric field is necessary for current to flow in a circuit.
What is needed to produce electromagnets?
electric current
Which of these is needed to operate on an electric motor?
alternating current
Which of these is needed to operate an electric motor?
alternating current
What provides an electric current in an electromagnet to generate magnetic fields?
An electric current flowing through a coil of wire provides the energy needed to create magnetic fields in an electromagnet.
Is galvanometer generator alternating current or direct current needed to operate an electric motor?
That depends if it is an ac or dc motor.
What is needed for electromagnetic induction?
An electric current is produced by the change in Magnetic flux over timeRead more: How_do_electromagnets_work
What is the continuous flow of electric charges through a material?
Yes, an electric current is the flow of charged particles.
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 the direction of flow of electric current in an electric current?
DC current
What is the opposite of a electric current?
The opposite of an electric current is the absence of an electric current, meaning no flow of electric charge through a conductor.
What is a wedding voltage?
A wetting voltage is a minimum electric current needed to break through the surface film of a contact. This film occurs most in areas of high humidity, and as such wetting current is needed for systems with delicate switches.
What is a continuous flow of electricity is called?
A current.
