Is voltage drop across each device the same in household circuits?
No, even though these are parallel circuits, the voltage drop across each device is not the same in house hold circuits, or anywhere, for that matter. Different devices pull different currents. A toaster, for instance, pulls many times what a light bulb pulls. Since wires do not have truly zero resistance, those differing currents result in different voltage drops across the wires that lead to the devices. That small voltage drop in the wires results in a different voltage drop across each device, even though the device/wire is connected to the same voltage source.
Can a series circuit have one electrical device?
No. You can have multiple devices on a series circuit. How about a low voltage Christmas tree light set. There you may have 15 or 20 lamps in series.
How does voltage fluctuation affect an electrical system?
Whenever you are working over a device and getting a constant voltage supply ,, and all of a sudden .. the light gets off and the device is off. it means a device was working over some specified voltage and it comes to 0 instantly . the voltage changes . this is called voltage fluctuation .
Can higher voltage burn the fluorescent bulbs?
it all depends on the voltage the light bulb can sustain.
How does a voltage detector work?
A voltage detector works by sensing the presence of an electric field around a live wire or electrical device. When the detector is brought near a voltage source, it detects the electric field and indicates the presence of voltage, usually through a light or sound signal. Some detectors use capacitive coupling to measure voltage without direct contact, while others may require contact with the conductor. They are commonly used to ensure safety when working with electrical systems.
What is a photovoltaic and how does it work?
A photovoltaic cell is a device that converts light energy into electrical energy. When sunlight hits the cell, it excites electrons in the material, creating a flow of electricity. This electrical energy can then be used to power various devices or stored in batteries for later use.
What does the oil pressure sensor do?
Obviously asits name implies it senses oil pressure. If it is for a gauge it usually is a device that changes resistance or generates a voltage as the pressure on it changes. If it is for a warning light it is usually a spring loaded switch.
What does photovoltaic stand for and why?
The term means: capable of producing a voltage when exposed to radiant energy, especially light. Photo-=light (photons are what light is made of) + -volt- =voltage (or electric current) + -ic = pertaining to. Pertaining to something that can produce voltage from sunlight.
Which device convert light signals on fiber optic cables into voltage?
fiber conventer
How does a thermocouple work on a gas boiler?
A Thermocouple is simply a temperature-sensor consisting of a junction between two metals, where the tiny voltage between them varies with temperature. This change in voltage can be detected and acted upon by the electronics controlling such things as boilers.
What is a device that contains vanes that move when exposed to light?
A solar-powered actuator is a device that contains vanes that move when exposed to light. This movement is achieved through the conversion of light energy to mechanical energy, often used in applications such as solar tracking systems for solar panels or sun tracking devices in architecture.
Please explain the charging circuit in automobile. 1. How does the charging light comes on when ignition switch is turned on 2. How charging light comes on when alternator is not or less charging?
When the ignition is turned on, battery voltage passes down the wire to the alternator to 'excite' the alternator when the engine starts. When the engine starts and the alternator generates a voltage, the light is extinguised by the charging voltage cancelling out the battery voltage coming down the wire. If and when the alternator completetly fails the the light will come back on as there is no sancelling voltage. if the alternator produces a voltage lower than the voltage from the ignition switch then the battery light will glow.
What device is known when electrons are emitted when light shines on a metal surface?
The device you are referring to is a photoelectric cell or a photodiode. When light shines on the metal surface of these devices, electrons are emitted in a process called the photoelectric effect, which generates an electric current.
What type of device lights up when a small voltage is applied across it?
An LED (Light Emitting Diode) will fit into this category, or a torch (flash light) bulb.
How does a yo yo light up?
Some lighted yo-yos have small batteries that light them as they spin. More rarely, there is a friction device that generates energy from its spinning to power a small LED.
What is a thermogenerator on gas logs?
Also known as a thermocouple- device generates very small eletrical current from heat of the pilot light, which permits gas valve to open only when pilot light is lit.
