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.
Can you put low voltage sound wires and low voltage light wires in the same conduit?
noyou can not
What is a photovoltaic and how does it work?
It is basically a photodiode with no reverse biased voltage is applied to it . it generates the potensial across it when exposed to light
What is a device that contains vanes that move when exposed to light?
radiometer
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
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 is intrinsically safe flash light?
A device that is sealed and will not allow its potential internal hazard be exposed to its external environment.
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.
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.

What are characteristic of star?
It shines (it generates light).
