What else can I help you with?
Will a photocell work using dc voltage?
it creates a dc current
Does resistance depend upon current?
The higher the resistance the lower the current flow. It restricts the flow of electrical current. The resistance will not depend upon the current. The current flow will depend on the resistance.
What equation relates power to current and resistance?
Power = (current) times (voltage)Current = (Power) divided by (voltage)Voltage = (Power) divided by (current)
How does current depend on resistance?
Pressure from the voltage.
Frequency depends on voltage or current?
Frequency doesn't depend on either voltage or current.
When light strikes a photocell does the resistance increase or decrease?
When light strikes a photocell, the resistance decreases, allowing current to flow more freely.
How do you reset photocell?
To reset a photocell, first, turn off the power supply to the device for about 10-15 seconds. Then, restore the power, allowing the photocell to recalibrate itself. If it has a reset button, press it according to the manufacturer's instructions. Finally, ensure that the photocell is clear of any obstructions or dirt that might affect its operation.
Will a photocell work using dc voltage?
it creates a dc current
How many current produced in photocell?
The amount of current produced in a photocell depends on the intensity of light that hits the cell. Higher light intensity will generate more current, while lower light intensity will generate less current. The current produced is generally in the range of microamps to milliamps.
How does a photocell convert light into electrical energy?
A photocell contains semiconductor materials that generate charge carriers when exposed to light. The photons in the light provide energy to these charge carriers, creating an electrical current as they flow through the semiconductor material. This current can then be used as electrical energy.
What happens if gamma rays falls on a photocell?
Gamma rays typically have enough energy to ionize atoms in the photocell material, releasing electrons. This can result in a current being generated in the photocell, which can be used to detect the presence of gamma rays.
In a photocell light energy is converted into?
In a photocell, light energy is converted into electrical energy. When light strikes the photocell surface, photons of light are absorbed, releasing electrons that create an electric current.
How do you replace a photocell on your outdoor light post?
# Turn off the power to the lamppost circuit at the breaker box. # Unscrew the mounting screws holding the lamp in place, and pull the lamp fixture from the post. Remove the wire nuts, and use the circuit tester to be sure the power is off. # Disconnect the wires to the fixture and the photocell. # Disconnect the locking nuts that hold the existing photocell on the post, and remove the photocell. If your lamp doesn't have a photocell, you'll need to drill an access hole in the post to install one. # Install the adhesive foam ring (provided with the photocell) around the mounting hole. # Run a bead of silicone sealant around the photocell where it will press against the interior of the lamppost. # Push the sensor through the mounting hole, and secure it with a locking nut. # Add silicone sealant inside the lamp fixture at any point where moisture might leak through to the photocell. # Connect the white wires from the power supply, lamp, and photocell together. Secure the connection with a wire nut. Connect the black photocell wire to the black power supply wire in the same manner. Connect the black lamp fixture wire to the red photocell wire and secure the connection with a wire nut. # Reainstall the fixture on the lamppost.
How does a photocell work in a kerosene heater?
A photocell in a kerosene heater works by using light to generate an electrical current. The photocell detects the flame produced by the heater and triggers the fuel pump to continue supplying kerosene. If the flame goes out, the photocell senses the absence of light and shuts off the fuel supply to prevent dangerous fuel leaks or build-up.
What type of material is a photocell made from?
A photocell is typically made from a semiconductor material such as silicon. When light strikes the semiconductor material, it generates an electric current, making it a key component in light-sensing devices.
How do you change an outdoor sensor light fixture photocell?
To change an outdoor sensor light fixture photocell, first, turn off the power at the circuit breaker to ensure safety. Remove the light fixture from its mounting, typically by unscrewing it from the wall or ceiling. Locate the photocell, which is usually a small cylindrical or rectangular component, and disconnect the wiring by unscrewing it or unclipping it. Replace it with a new photocell, reconnect the wiring, and reassemble the fixture before restoring power.
What two factors does the power of a light bulb or appliances depend on?
The power of a light bulb or appliance depends on its voltage (V) and current (I). The power (P) can be calculated using the formula P = V x I.
