Electric currents are caused by voltages.
The flow of current in a material is controlled by its conductivity, which is influenced by the presence of an electric field. When an electric field is applied, it can cause charged particles in the material to move, resulting in the flow of current. The conductivity of the material determines how easily current can flow in response to the electric field.
Increasing the electric field magnitude along a wire will increase the current density. This is because a higher electric field will cause more electrons to move through the wire, resulting in a higher flow of electric current.
A wire cannot cause a magnetic field if there is no current flowing through it. Magnetic fields are generated by the flow of electric current in a conductor.
Yes, when an electric current flows through a coil wired to an electric bell, it creates a magnetic field. This magnetic field causes the coil to move and strike a bell, producing a sound.
The opposite of an electric current is the absence of an electric current, meaning no flow of electric charge through a conductor.
Yes, a MOVING magnetic field will cause electric current to flow in a conductor. Conversely an electric current flowing in a conductor will cause a magnetic field.
An electric current is movement of electrons, no matter the source or cause.
The ability of light to cause electron movement and electric current is known as the photoelectric effect. When photons of light strike a material, they can transfer their energy to electrons, causing them to be ejected from the material, which can then result in the generation of an electric current.
very severe can cause death
yes
Chemical changes, change in magnetic flux linked with a conductor cause the production of electric current.

6 MilliAmps across the heart.
It causes a proportional increase in current.
Yes, during the ionic foot detoxication electric current runs through the body of the given patient. The electric current is however very low to cause harm to the body of the patient.
Increasing the electric field magnitude along a wire will increase the current density. This is because a higher electric field will cause more electrons to move through the wire, resulting in a higher flow of electric current.
