### What happens to the energy when you turn on an electric lamp?

Electricity flows through the filament, resistance in the filament causes heat and light energy to be created.

### Property of the filament that makes it light up when electricity flows through it?

Incandescence. The filament is heated by the electricity moving through it, this causes the filament to heat up, and the heat causes the familiar glow.

### When electricity flows through the metal filament of a light bulb electrical energy is converted to?

Heat, which then produces light.

### What is the property of the filament that makes it light up when electricity flows through?

the simple answer is resistance, the filament is a very fine wire (usually tungsten) that heats up and glows when power is applied

### What is the property of filament that makes it light up when electricity flows through it?

the simple answer is resistance, the filament is a very fine wire (usually tungsten) that heats up and glows when power is applied

### Does a light fitting still use electricity if it's on but the bulb has blown?

No. The filament completes the circuit, so if the filament is blown the circuit is incomplete, so no electricity flows.

### Why does the light bulb not work when the filament is broken?

A light bulb works by passing an electric current through the filament, which is usually made from a high resistance substance such as tungsten. When the current flows through, the filament glows which produces the light. When it burns out, no electricity passes and no glowing occurs. Source: i just know

### Can a bulb light up if no electricity is running through to it?

Simply put, no. A light bulb lights up because the filament inside (the thin wire that often breaks) has a lot of resistance in it, then when electricity flows through it, it heats up and glows brightly.

### What happens to the electricity as it flows through the closed circuit?

Some is changed into light and heat energy and some continues through the curcuit

### 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.

### What happens to the electricity when there is only one switch?

Electricity flows in a complete circuit

### How is electricity produced in a flashlight?

When a flash light is switched on the circuit between the lamp and the batteries is complete. When the circuit is complete, the electrons flow from the positive terminal of the batteries through the tungsten filament back to the negative terminal of the batteries. Once the electricity flows through the filament it starts glowing producing a bright light. When the the torch light is switched off the circuit is broken and the flow of electricity is disrupted switching off the light.
