Why does the light bulb stay on when the switch is off?
When the light bulb stays on when the switch is off, it is likely due to a wiring issue or a faulty switch that is not properly cutting off the electricity flow to the bulb.
What does the switch do in a torch?
The switch in a torch controls the flow of electricity to the light bulb. When the switch is turned on, it completes the circuit and allows the electricity to pass through, lighting up the bulb. Turning the switch off breaks the circuit, stopping the flow of electricity and turning off the light.
How does a light bulb dimmer switch work to adjust the brightness of a light bulb?
A light bulb dimmer switch works by controlling the amount of electricity flowing to the light bulb. By adjusting the voltage, the dimmer switch can regulate the brightness of the light bulb.
Why doesn't a bulb light up until you press the switch?
A switch completes the circuit, allowing electricity to pass from the cell (battery) to the bulb.
How do you make bulb light using a switch?
In a theoretical ciucuit, a switch is not essential. What is needed is a source of electricity.
What describes electricity flowing from a battery through a switch to a light bulb?
A circuit
How does circuit stop flowing when light bulb switch is off?
The simplist answers is that electricity needs to complete a circuit fully. It stops flowing because there is no complete circuit. The switch is a device for opening and closing the circuit. When the switch is in the off position the circuit is said to be open and electricity cannot flow.
Why do bulb glow when you switch it on?
Because electricity flow through it's wire. Electricity came from outlets source. When you plugged in a device, electricity will flow into two ways. One is directed on a bulb and the other one is cut. Two points of cut wires are put in a switch so if you presses the switch, the other current (whether positive or negative) will generate full electricity that is capable of lighting a light bulb.
If a light bulb is burned out and the switch is on are you still using electricity?
A standard filament bulb works on the principle that it gets hot and glows when a current is passed through it. If the filament has burned out (blown) it is open circuit and no current can flow. Therefore you are not using any electricity even if the switch is still on It may still use power if it is a lighted switch. Find a licensed electrician at www.contraxtor.com
How does the power to light then switch work in electrical circuits?
The power to light switch in electrical circuits works by allowing or interrupting the flow of electricity to the light bulb. When the switch is turned on, it completes the circuit, allowing electricity to flow and light up the bulb. When the switch is turned off, it breaks the circuit, stopping the flow of electricity and turning off the light.
Why does the bulb not light until you press the switch?
there is no electricity running thru the wires yet
Does electricity flow through a light when the light is turned off?
The OFF position on the light switch interrupts the flow of electricity to the light bulb. If the switch is ON, there is always electricity at the light socket, even when the light bulb is removed. if the lamp is still pluged in electricity is still flowing through the lamp even if it is off or on
