Why dimmer switches feel hot?
If it is dimming the light, yes. A dimmer switch is nothing but a potentiometer, better explained as a variable resistor. It will lower the voltage going to the light bulb, but the excess energy must go someplace, and is released as heat. The lower the brightness, the warmer it will get (until it is turned all the way off). There are newer dimmer switches that work in different manners, but I don't believe that is what you are referring to.
Does a dimmer switch rheostat consume the electricity that the light fixture is not receiving?
A little. First off, most modern dimmer switches aren't rheostats. Those have been supplanted by TRIACs (triode for AC), and later, IGBTs (insulated gate bipolar transistors). For both of these, their mode of action is to change the duty cycle of the AC wave (duty cycle is time on versus cycle time) such that less power per cycle is put through the bulb. This is more efficient than a rheostat, in that, there isnt as much resistive loss across the dimmer. The resistive loss is where the "a little" comes in. For all three types, a small amount of the power put through the dimmer is dissipated as heat - however, this is significantly less than the reduction in output power to the bulb, whatever the type. An ideal dimmer would have 100% efficiency - that is, for a given setting, it would dissipate no heat, and the bulb would be the only thing on the circuit consuming power. However, no component is ideal, and modern dimmers typically consume under 1% of their power throughput (so if it's passing a total of 1W, it'll consume less than 10 milliWatts).
Why would pushing the brake on 1986 300zx make you lose electrical power?
Check for a short in the brake light circuit. A dead short will dim lights & blow fuses. Have you checked the charging system & battery? Pull the fuse for the brake lamp circuit & see if the same problem still exists.
What unit is used to measure voltage drop?
Voltage drop is typically measured in units of volts (V). It is a way to quantify the loss of voltage as electrical current flows through a circuit due to resistance. Voltage drop can be calculated by measuring the difference in voltage between two points in the circuit.
Voltage Magnification occurs in?
Voltage magnification occurs in transformers, where the secondary voltage produced is higher than the primary voltage input due to the ratio of the number of turns in the coils. This allows for efficient transmission of electricity over long distances with minimal power loss.
2004 Jeep Liberty Sport What could cause a loss of all the instrument cluster lamps when the fuse tests good The Dome lights work but no cluster lights in the dash radio blower or shift console?
I'm just making a guess here. There is a instrument panel dimmer switch on the multi-function lever on the left side of the steering wheel. This lever incluces turn signal, head lights, parking lights, hi/low beam, instrument panel dimmer, dome lights, and maybe some other stuff. One you figure out how to activate the dome/courtesy lamps, just back that part of the switch off one click and that is the maximum dashlight level setting.
Why do you lose power when adding a 12 volt switch?
Need more info.What are you powering?What is your supply in voltage and amperage?What type of loss are you getting.

How the length and thickness of wires could affect the brightness of light bulbs?
Voltage loss. On a long run you will loose some voltage so it is sometimes necessary to increase the wire size to compensate for the voltage loss. This loss of voltage will cause a light to be dim as it is not receiving the correct voltage that is was designed to use.
What is the difference between voltage drop and power loss?
voltage drop is the loss or drop that occured across the element so that voltage gets down and current increases across the element and power loss is like i2r loss and like wastage of power without consuming
What are the differences between series circuit lights and parallel circuit lights in terms of energy changes?
In a series circuit the lights share the voltage between them equally and the current stays the same throughout and if one bulb fuses the the other will not work. For the parallel, the voltage is the full voltage from the battery in all bulbs and the current is split between the different routes, and if one goes out the other one will stay lighten.
Is core loss same as no load loss in transformer?
Yes, that is almost true, apart from a very small copper loss in the primary winding that carries the small magnetising current. The core loss (iron loss) depends on the applied voltage. This loss is measured by the open-circuit test, carried out at the working voltage.
What is the voltage loss over 400 feet?
To answer this question the supply voltage and the amperage of the load must be given.
I had a new alternator and battery put in my 1999 subaru outback and now the low beams wont work.Could a new alternator have blown out the bulbs on both lights What else could be wrong?
That seems very odd, I wouldn't think the alt or bat change would have anything to do with loss of your low beams, Are you low beams actually burnt out or are they not getting power?? check this. could be a fuse or likely in the Dimmer switch in your steering colum.

What is the effect of diode voltage drop as the output voltage?
The effect of diode voltage drop as the output voltage is that the input voltage will not be totally transferred to the output because power loss in the diode . The output voltage will then be given by: vout=(vin)-(the diode voltage drop).
Why core loss depends on voltage?
Core loss depends on voltage because it is primarily due to hysteresis and eddy current losses in the magnetic core material. When the voltage increases, it leads to higher magnetic flux density variations within the core material, causing an increase in hysteresis and eddy current losses, thus resulting in higher core losses.
