What else can I help you with?
An electric dimmer switch for lights could raduce the light output by?
An electric dimmer switch for lights can reduce the light output by adjusting the amount of electrical current flowing to the light bulb. By decreasing the current, the dimmer switch can lower the brightness of the light emitted.
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?
Increasing the intensity of light or using a shorter wavelength light source can cause an electric current to flow in a photoelectric effect experiment. The energy of the photons should be increased to overcome the work function of the metal surface, allowing electrons to be ejected and generate a current.
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 you flip a switch on a flashlight?
When you flip a switch on a flashlight, you complete an electrical circuit that allows a current to flow from the battery to the light bulb. This causes the light bulb to emit light and illuminate the surroundings.
When you open the switch what happen to the bulb?
If the switch is in the off position, the circuit will be broken and the electric current can't flow to the bulb, so the bulb will not light up.
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.
If an insulator with a lamp is connected in a electrical circuit The switch is turned-on What happens?
If an insulator with a lamp is connected in an electrical circuit and the switch is turned on, the lamp will not light up. Insulators do not allow the flow of electric current, so the circuit will not be completed, and no electricity will reach the lamp to cause it to light up.
How do I turn on the light on an electric bike?
To turn on the light on an electric bike, locate the switch or button on the handlebars or near the display panel. Press or toggle the switch to activate the light.
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.
What happens when someone is shocked by a light switch?
When someone is shocked by a light switch, it means that they have received an electric shock from the switch. This can happen if there is a fault in the wiring or if the person touches the switch with wet hands. Electric shocks can range from mild to severe, and can cause injury or even death in extreme cases. It is important to be cautious around electrical devices to avoid getting shocked.
