A "diode" is any of several devices; the only thing they have in common is that they have two electrical connections - hence the name. These devices have different functions. The simplest semiconductor diode, and one of the most common, is probably the rectifier diode. It lets current pass in one direction, but not in the other direction.
What else can I help you with?
What happens when too much electrical current passes through the metal strip on a fuse?
It will burn out.
When current passes through a wire?
When current passes through a wire, it creates a magnetic field around the wire. The direction of the magnetic field is determined by the direction of the current flow. This principle is the basis for electromagnets and various applications in electrical devices.
What energy transfer takes place when the current passes through a resistor?
When current passes through a resistor, electrical energy is converted into heat energy, which causes the resistor to heat up. This process is known as Joule heating.
How does a resistor work in a circuit to regulate the flow of electrical current?
A resistor in a circuit works by impeding the flow of electrical current, which helps regulate the amount of current passing through the circuit. This is achieved by converting electrical energy into heat energy as the current passes through the resistor, limiting the flow of electricity.
Why Does a bulb glow when an electrical current passes through it?
When an electrical current passes through a bulb, the electrons in the filament (usually made of tungsten) gain energy and move to higher energy levels. They then release this energy in the form of light and heat, causing the bulb to glow. This process is called incandescence.
When an electrical current passes through water what takes place breaking down the compound into hydrogen and oxygen?
A Chemical Change :)
Why does the current loose some of the energy when it passes through a bulb?
When current passes through a bulb, it encounters resistance in the filament of the bulb. This resistance causes some of the electrical energy to be converted into heat and light, resulting in a loss of energy in the form of heat radiation.
Does the resistor store some energy?
No, resistors do not store energy. They dissipate electrical energy in the form of heat when current passes through them.
What is a circuit which produces a magnetic field by an electrical current called?
That would be an electromagnet. It consists of a coil of wire through which an electric current passes to generate a magnetic field.
Whichof these is the best definition for electrical current?
Electrical current is the flow of electric charge in a circuit, typically carried by electrons through a conductor. It is measured in amperes (A) and indicates the rate at which electric charge passes through a given point in a circuit over time.
If an electrical current passes through a conductor what two things are generated?
If an electrical current passes through a conductor, there is an induced voltage (because no conductor has perfectly zero ohms), resulting in power dissipation, and there is a magnetic field, which can interact with other conductors in the vicinity of the first.
When current passes through a conductor what makes the conductor heat up?
When current passes through a conductor, the electrons in the conductor collide with the atoms, creating resistance. This resistance causes the electrons to lose energy in the form of heat, which increases the temperature of the conductor.
