How the severity of an electric shock depends on the current and voltage?
he severity of injury from electrical shock depends on the amount of electrical amperage (current) and the length of time the current passes through the body For example, 1/10 of an ampere (amp) of electricity going through the body for just 2 seconds is enough to cause death.
What happen when ac current passes through resistor?
it resists the flow of cuurent
Why must the instantaneous current wave be exact 90 degree out-of phase with the applied voltage waveform across an ideal inductor?
Because the voltage induced is proportional to the rate of change of current, and the maximum rate of change of current occurs at the point where the current waveform is 'steepest' -i.e. as it passes through zero. So, as the current passes through zero, the corresponding value of induced voltage is maximum, which means the voltage and current waveforms are displaced by a quarter of the wavelength, or 90 degrees.
What is another name for a bulb in a circuite?
Another name for a bulb in a circuit is a "lamp." In electrical terms, it refers to a device that produces light when an electric current passes through it. Lamps can come in various types, including incandescent, LED, and fluorescent, each functioning to convert electrical energy into light.
Do charges move from a source of potential difference into a load or through both the source and the load?
As the circuit must be a closed loop, the current passes through both the source and load. If it was not a closed loop no current could flow anywhere.
What happens to the electrical energy carried by the current when it passes through the filament of a bulb?
it stays there. the electricity travels back and forth through the filament until you turn the lighbulb off.
What happens when an electric current passes through steam?
When an electric current passes through steam, the steam gets ionized and conducts electricity. This can lead to the formation of plasma, which is a highly energized state of matter. The steam may break down into its constituent gases, hydrogen, and oxygen.
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 if a current passes through solenoid If yes then what happens in the whole process?
Yes. DC can pass through. As it passes through then solenoid would act as if a bar magnet.
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.
What happens when electric current passes through the acidulated water?
Water is dissociated in hydrogen and oxygen.
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.
What happens when an electric current passes through a wire?
When an electric current passes through a wire, the flow of electrons creates a magnetic field around the wire. This phenomenon is known as electromagnetism. The strength of the magnetic field is directly proportional to the amount of current flowing through the wire.
When an electrical current passes through water what takes place breaking down the compound into hydrogen and oxygen?
A Chemical Change :)
What happens to a wire when and electric current passes through it?
When an electric current passes through a wire, the wire heats up due to the resistance in the material. The current causes electrons to flow through the wire, creating a magnetic field around it. This effect is used in electromagnets and electric motors.
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.
