What is the ability of light to cause electron movement and electric current?
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.
If you are running a photoelectric effect experiment and your light source cannot create an electric current which adjustment might cause an electric current to flow?
Increasing the intensity of light or using a shorter wavelength light source can cause an electric current to flow in a photoelectric effect experiment. The energy of the photons should be increased to overcome the work function of the metal surface, allowing electrons to be ejected and generate a current.
What must pass through a coil in order to make an electromagnet?
An electrical current will cause an electromagnet to energise.
A potentially lethal electric current is on the order of?
A potentially lethal electric current is typically on the order of 100 milliamperes (mA) or higher. Currents as low as 10 mA can be dangerous if they pass through the heart. It's important to remember that even lower currents can cause harm depending on the specific circumstances.
What force creates a magnetic force?
Typically, an electric current creates a magnetic force. Also, magnetic domains aligned correctly and properly can cause a magnetic force.
Can Magnetism cause an electric current to flow in 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.
Does electric current cause a coil wired to become an electric bell?
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.
What particles create the electric current in a fruit battery?
An electric current is movement of electrons, no matter the source or cause.
What is the ability of light to cause electron movement and electric current?
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.
How severe an electric current can be?
very severe can cause death
Does moving an electric current cause a magnetic field?
yes
What most occur to produce electric current?
Chemical changes, change in magnetic flux linked with a conductor cause the production of electric current.
Why current is lower when the cable is coiled up?
When a cable is coiled up, it can create additional resistance due to increased inductance and potential skin effect, which can limit the flow of current. The coiling can also cause the magnetic fields around the wire to interact, leading to energy loss in the form of heat. Additionally, if the coiled configuration leads to tighter turns, it can increase the impedance in the circuit, resulting in lower current flow. Overall, these factors contribute to a reduction in current when the cable is not fully extended.
What controls the flow of current with an electric field?
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.
How much electric current can cause death?
6 MilliAmps across the heart.
What does an increase in voltage cause in an electric circuit?
It causes a proportional increase in current.
How can an electric current cause an iron nail to become a temporary magnet?
When an electric current flows through a wire wrapped around an iron nail, a magnetic field is created. This magnetic field aligns the magnetic domains within the iron nail, causing it to become magnetized. Once the current stops, the magnetic field dissipates, and the nail loses its magnetism.
