What energy takes place when turning on a flashlight?
electrical energy
What happened to the light bulb when the switch was off what does it indicate?
When the switch is ON the bulb and resistor are “shorted” and the neon bulb does not glow. When the switch is OFF the neon bulb and resistor are still in-circuit across the (open) switch contacts. The bulb and resistor can provide a path for leakage current.
Do LED flashlight bulbs break?
According to an article in The New York Times, a standard incandescent bulb will last 1,000 to 2,000 hours in its lifetime, while an LED will last 25,000 to 50,000 hours. This doesn’t explain, though, how long a flashlight will stay illuminated at one time.
Which light bulb will be turned off by the open switch?
In series circuits, when either or both of the switches, are open, power will not flow and the light bulb will be off. Only when both switches are closed, does power flow and the light bulb illuminates. Said another way, if both switch A and switch B are closed, then the light will turn on.
When the light is on is the circuit open or closed?
Technically, that’s creating an open circuit. A flashlight that is off is an open circuit.
What happens when the switch is closed in a circuit?
When a switch is closed current flows through it.
Which condition result in open circuit?
An open circuit is one where the continuity has been broken by an interruption in the path for current to flow. A closed circuit is one that is complete, with good continuity throughout. A device designed to open or close a circuit under controlled conditions is called a switch.
What happens in a short circuit?
They occur when a low-resistance path not suited to carry electricity receives a high-volume electrical current. In simpler terms, short circuits happen when hot wire touches a conductive object it’s not supposed to. The result of a short circuit can be appliance damage, electrical shock, or even a fire.
