When an electrical switch is in the off position, the circuit is interrupted. When the switch is on, the circuit is open and complete.

Which adjustment might cause an electric current to flow?
Switch to a light source with a shorter wavelength.... Switch to a light source with a higher frequency
If you are running a photoelectric effect experiment and your light source cannot create an electric current which adjustment might cause an electric current to flow?
- select the adequate material for this experiment - switch to a light source with a shorter wavelength - switch to a light source with a higher intensity
What would happen if there is no an electric switch in a curcuit?
Generally we use electric switches to put on or off the light,fan,computer,music system,etc.An electric switch is a device that is used to open or close an electric circuit.when we open an electric circuit the flow of electric current inthe circuit stops and when we close an electric circuit an electric current flows through it.
How does a pilot light switch work?
It senses heat and generates a tiny electric current that triggers a valve in the regulator.
What happens when we switch on the tube light does current flow through it or voltage?

What happens when the switch is open in a circuit containing wires a light bulb a switch and a battery?
When you open a switch to a light for example, you cause a break in the flow of current to the light. Opening a light switch means you are turning the light off by stopping the flow of current to it. Closing a switch means you have completed a circuit (basically a loop) and current now flows causing the light to go on. Think of electricity like water. To cause your bath tub to fill up (light on) you have to also complete the circuit by turning the tap. Now we have water flow. (current) To stop the flow of water, we want to open the circuit by turning the tap in the opposite direction causing a break in the flow of water.
What is the ability of light to cause electron movement and electric current?
The photo-electric effect is the ability of light to cause the movement of electrons, which is called an electric current.
Why starter used in tube light fitting?
The starter is used to help the lamp light and acts like a closed switch. It allows electric current to flow through the filaments.
Does an electric current reflect or refract light?
No. An electric current has magnetic properties,but not optical properties.
What will happen to the light bulb when you switch off the electric circuit?
There will no longer be current to heat the filament which will then cool and no longer emit visible light. While it is cooling it will continue to emit infrared light for a time.
How do you wire 2 light to the same switch?
by a parellal current switch.
What gives out a light if an electric current flows through it?
A light bulb in an electric circuit when electricity reaches it.
