## When electricity is passed through a bulb it gives?

The current flowing through the resistance of bulb causes the filament to dissipate energy in the form of heat and light. The filament is actually glowing white-hot because of the energy it is dissipating, thus giving off light.

## When electric switch is current flows through the circuit and bulb glows?

An electric bulb glows when electric current passes through it. In a closed electric circuit, the electric current passes from one terminal of the electric cell to the other terminal. Switch is a simple device that is used to either break the electric circuit or to complete it.

## When electricity passes through a bulb it gives off sound and light light only light and electricity light and heat?

Answer: an in incandescent bulb uses heat caused by an electric current. when electrical current passes through a wire it causes the wire to heat. the wire or filaments gets so hot that it glows and gives off light.

## How does a lightbulb produce light?

Essentially, the lightbulb is a very thin filament of hard-to-melt metal – tungsten, usually – encased in a glass bulb filled with inert gases so that the filament doesn’t oxidise and disintegrate. The electricity causes the wire to glow and a portion of that energy is turned into light.

## When electric current is passed through a bulb the bulb gives light because?

Explanation: Heating effect of electric current is responsible for the bulb to glow in an electric circuit. Due to heating effect, the filament of the bulb gets heated to a high temperature and it starts glowing.

## What happens when an electric current is passed through the filament of the bulb?

When electric current is passed to an electric bulb, resistance of the spring like structure joined between two points in the Bulb. This causes it to heat and hence it produces Light. It involves conversion of electrical energy to Light energy.

## Which part of the bulb glows when current is passed through it and name the material it is made up of?

When the terminals of the bulb are connected with that of the electric cell by wires, the current passes through the filament of the bulb. This makes the bulb glow.

## When the switch is on the electric circuit is?

An electric switch is a device that interrupts the electron flow in a circuit. Switches are primarily binary devices: either fully on or off and light switches have a simple design. When the switch is turned off, the circuit breaks and the power flow is interrupted. Circuits consist of a source of power and load.

## What is the role of a switch in a circuit Will the bulb glow in the given set up explain your answer?

Yes, the given object is a conductor as it allows the electric current to pass through it and causes the bulb of tester to glow.

## When electric current is passed through the filament of a bulb it gives off a sound B heat C magnetism and light?

When electric current passes through the filament of a bulb, it gives off heat and light.

## When electric current flows through a filament of electric bulb the filament gives out which energy?

When electric current flows through a filament of electric bulb , the filament gives out heat..
