What is electrical energy converted into when electric current flows through the metal filament of a light bulb?
Electrical energy is converted into light and heat when electric current flows through the metal filament of a light bulb.
When electric current flows through the metal filament of light bulb electric energy is converted to?
Heat and light.
Does current direction matter when lighting a light bulb?
No. In fact, if the light bulb is powered by alternating current (AC), as almost allhousehold lights are, then the current is changingdirection 100 or 120 times asecond anyway.
How much current flows in a 75-walt's light-bulb connected to a 110 voltage wall outlet?
The current flowing through the 75-watt light bulb connected to a 110-volt wall outlet can be calculated by using the formula: Power = Voltage x Current. Therefore, the current flowing through the light bulb would be approximately 0.68 amps.
What causes the bulb to light in a closed circuit?
In a closed circuit, electrical current flows from the power source through the wires, through the bulb, and back to the power source. When the current reaches the filament inside the bulb, it heats up and emits light, causing the bulb to light up.
What has to happen for the bulb to light up?
To light up, the bulb needs an electrical current flowing through it. This current is typically provided by connecting the bulb to a power source, such as a battery or outlet. Once the current flows through the bulb's filament, it heats up and produces light.
Is a light bulb an electromagnet?
No, a light bulb is not an electromagnet. A light bulb contains a filament that produces light when current flows through it, whereas an electromagnet is a device that produces a magnetic field when current flows through a coil of wire.
What is electrical energy converted into when electric current flows through the metal filament of a light bulb?
Electrical energy is converted into light and heat when electric current flows through the metal filament of a light bulb.
When lightbulbs are connected in a series how much current flows through each one?
same current flow in each bulb
What gives out a light if an electric current flows through it?
A light bulb in an electric circuit when electricity reaches it.
What is in a light bulb when it's switch is turned on or connected the electricity flows through what we call?
A closed current
When electric current flows through the metal filament of light bulb electric energy is converted to?
Heat and light.
How does the current from a charged capacitor light a bulb, and how does the brightness of the bulb change as time goes on?
When a charged capacitor is connected to a light bulb, the current flows from the capacitor through the bulb, causing it to light up. Initially, the bulb may be very bright as the capacitor discharges quickly, but as time goes on, the brightness decreases as the capacitor loses its charge and the current flowing through the bulb decreases.
When electric current flows through the metal filament of a light bulb electrical energy is a?
converted into heat and light energy.
Does current direction matter when lighting a light bulb?
No. In fact, if the light bulb is powered by alternating current (AC), as almost allhousehold lights are, then the current is changingdirection 100 or 120 times asecond anyway.
Is a light bulb an insulator or conductor?
It is a conductor, but the filament is a resistor : as current flows through the filament, some of the energy is released as heat and light.
What type of energy will turn on a light bulb?
Electrical energy will turn on a light bulb. When the electrical current flows through the wires in the bulb, it creates heat and light, illuminating the bulb.
