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.

Which bulb will glow at first when 3 bulbs are connected in series and switch is connected after 1 bulb?
All the three would glow at the same instant.
What happens when a bulb ammeter battery and switch are put connected together?
the bulb will glow and ammeter will show the reading
Three different bulbs are connected in series when switch is closed the last bulb does not glow why?
because the switch is closed
How do you know that house lights are wired?
When you turn the light switch to the up (on) position, if the bulb is not burned out, the light bulb will glow.
Would a bulb glow if you put a rubber as the switch in a circuit?
because rubber is an insulator
What bulbs glow when switch A is closed and switches B and C are open?
it's bulb 3
What describes electricity flowing from a battery though a switch to a light bulb?
Circuit Electrons flow form the positive end of the battery through the wire connecting the positive terminal to a switch. The other end of the switch is connected to one terminal on the bulb, the other terminal of the bulb is connected to the negative end of the battery. No electrons (current) flows as long as the switch is open. Once the switch is closed and if the battery has enough voltage and current capacity to make the filament in the bulb glow, then the bulb emits light (together with wasted heat). If the switch is open, no current flows through the entire circuit and the bulb does not glow.
How do you make a bulb which glow on your clapping bulb?
you have to need IC 3 ,bulb
What happens when a battery light the light bulb?
When the switch is turned it completes an electrical circuit. The circuit amperage flows through a high resistance filament in the bulb and it starts to glow. The bright glow from the filament and the reflector behind the bulb is what creates the flashlights beam.
What components do you need to make a simple series circuit to light on bulb?
You need a Battery, Light Bulb, Ammeter, Switch.
Can a tomato glow when connected to a light bulb?
no
How does removing a bulb or opening and closing the switch affect a parallel circuit?
it is because the energy flows through the switch and it makes the light bulb turn on and if the switch is open the energy will not flow it will stay in the place the switch begins
