What causes passengers airbag light to flicker dimly?

I had same problem it was the alternator acting up 2mnths later the alternator failed completely Some vehicles have weight sensors in the passenger seat. If there is approx 15 pounds in the seat (the weight of a infant seat) the pass light comes on and the airbag shuts off. If your vehicle is equipped that way you may have a malfunction with that system.

If your dimmer switch goes out will it make your lights not work?

If a dimmer switch goes out, it may cause the lights to not work at all or to stay at a single brightness level. This can be due to a faulty switch or wiring connection. It is important to check the switch and wiring to determine the cause of the issue and resolve it accordingly.

How many watts are in 300 volts?

Watts = Volts x Amps x Power Factor. So as you can see watts and volts are different units and you need to know more information. So if you had 1 microamp of current and 3 million volts you would only have 3 Watts.

How does GPS know where you are?

A GPS receiver determines its location by analyzing signals it receives from GPS satellites orbiting around Earth. Signals from satellites that are farther away take longer to reach the GPS receiver. Distances to several satellites are calculated based on the amount of time their signals took to reach the receiver. After determining its distance from at least three satellites, the GPS receiver can calculate its own position using triangulation. (Any location can be identified using distances from three other know locations.)

How many DC amps are in an AC amp?

Watts in AC are the same as watts in DC.

A watt is a unit of energy transfer, in units of joules per second. You calculate watts by multiplying volts (joules per coulomb) by amperes (coulombs per second).

While watts are still watts, AC or DC, the calculation becomes more complex in AC for multiple reasons. Current is often not in phase with voltage due to capacitive or inductive reactance. This leads to additional terminology such as vars (volt-amps-reactive) and power factor (ratio of true vs apparent power). Current is often not continuous over the entire AC cycle, making the voltage or current (and thus the power) cycle non-sinusoidal. (In a power supply, for instance, current flows only when the input AC voltage is above the rectifier's forward breakdown voltage, and this only occurs as a pulse in the cycle when the filter capacitor needs to be recharged.)

What is the meaning of solid wire?

Wire can be fabricated in two different forms. Solid wire refers to a single wire, while stranded wire is a wire which is made up of more than one single solid wire twisted together. A stranded wire is much more flexible, and less subject to breaking from flexing than a stranded wire of the same size.

What can you power off a 1200 watt generator?

A 1200 watt generator can typically power small appliances such as a refrigerator, microwave, computer, TV, lights, and fans. It may not be able to power larger appliances like air conditioners or washers and dryers. Be sure to check the specific power requirements of your appliances to ensure they can be safely powered by the generator.

Does pencil lead conduct electricity?

Pencil lead (aka graphite) DOES conduct electricity. It does this thanks to electron delocalization within the carbon layers. Since the valence electrons are free to move, they are able to conduct electricity.

What do the letters in T 6.3 A L 250V stand for?

T means Slow blow , 6.3A is the maximum current this fuse will conduct , any more and the fuse will heat up and melt the conductor .

Maximum voltage capacity is 250V , this means the maximum voltage that the fuse can block from "jumping" . It means you can use it in a system from 0 - 250V with a maximum current handle of 6.3A .

Lead acid battery epsom salts?

I have of course read much about the item of reconditioning acid lead battery by Epsom salt. My car battery was on its way of becoming bad (no longer able to attain a good specific gravity of the acid solution through charging it at home). During last charging despite using the max. current and time a sp. g. higher than 1.235 could not be attained. After adding about 15 ml of powder (dissolved in about 25 ml warm distilled water) to each cell I could bring the sp. g. to over 1.275. This fantastic rise I could never achieve before . I conclude that Epsom salt not only can be used to revive a dead acid lead battery but also prophylactically to maintain the battery in good condition and prevent its deterioration. I must also add that I by now do not know the prognosis of this practice on the long run. I was just struck by its ability to improve the battery condition so much! It is a marvellous agent.

What are framing bits used for?

Framing bit is a common practice in telecommunication. Framing bit is a bit that precedes a T1 or J1 frame. It is used for the purpose of synchronization of the incoming data with the receiver.

Define the difference between a primary and secondary cell?

Cell culture is the complex process by which cells are grown under controlled conditions. The growth of explants taken directly form the living organism (e.g. biopsy material) is also known as primary cell culture. The culture consists of mixed population of cell types. Frequently the some of the cells may survive without proliferating and will therefore be lost in the increasing population of those which are able to multiply in the conditions supplied in vitro. Cells from explants may sometimes be converted to cell lines by passage. These may continue to proliferate for a number of cell generations. In some instances the primary cells are fused with so-called immortal (cancer) cells to produce a hybridoma line. Many of the explanted cells will only survive for one or a few passages before dying.

How does gps work?

GPS receivers integrate a radio and a navigation computer and can receive the faint, twenty-watt signals coming from the satellites. The computer uses these signals to calculate the distance between the satellites and the receiver. With this information, the computer can further calculate the position and velocity of the receiver.

The number of satellites visible to a receiver constantly varies between four and eleven according to time and location. Each satellite broadcasts a number of unique spread-spectrum codes, but only one, the Coarse Acquisition (C/A) code, is easily accessible for civilian use.

On the ground all GPS receivers have an almanac programmed into their computers that tells them where in the sky each satellite is, moment by moment.

How do you get cover of dome ceiling light fixture to change light bulb?

It depends on the fixture. I have 4 types. One has screws on the outside of the metal frame, so you unscrew those and hold the glass bowl. Another has two big metal clips INSIDE the glass bowl. I have to be brave and just pull to one side until the first side unclips - putting it back on is more nerve wracking! Another has a metal pole coming through the center of the dome. Hold on to the glass, but pull the metal piece a bit to one side and then unscrew it. The final one almost stumped me - an electrician purchased it and installed it this winter and I never thought about changing the bulb! There is no metal pole, no screws, just the frame and the dome. You have to TWIST the glass counterclockwise and it unscrews (there are three metal bumps on the INSIDE that hold it when you screw it back. hope this helps!

And I found a fifth: Hold metal frame and pull down on glass fixture. One side started coming out giving me confidence to pull more. I finally removed the glass and found three Spring Clips that hold the glass fixture. I strongly suggest that this is the last method you consider.

How do you program a new sliding gate remote rc434?

Why did old fashioned camera light bulb burst?

Old-fashioned camera light bulbs could burst due to a variety of reasons, such as excess heat buildup inside the bulb, manufacturing defects, or physical damage to the bulb. The intense heat generated by the bulb during use could cause the glass to expand and contract rapidly, leading to its eventual failure.

Can lead conduct electricity?

Yes, lead can conduct electricity, but it is a poor conductor compared to other metals like copper or aluminum. Lead is used in a variety of applications for its electrical conductivity properties, such as in soldering materials and electrical cables.

How much power is consumed by a load drawing 5a with 120v across it?

real P= V * I *cos(phase angle between V and I)
for purely resistive loads or DC voltages this equals real power P=V*I = 120*5= 600Watts
for not pure resistive loads you'd have to measure the phase angle between Voltage and Current to get real power.
However, at home, the utility company charges for Complex power = V*I.
So you'd still pay for V*I.

Wire a three-way switch One light controlled by two switches- similar to a hall ligt. SPDT switches?

To wire a three-way switch with SPDT switches for one light controlled by two switches, you will need to connect the common terminal of one switch to the hot wire coming from the power source, connect the common terminal of the other switch to the light fixture, and connect the two remaining terminals of the switches together with one wire. This configuration allows either switch to control the light. Be sure to follow proper wiring techniques and safety precautions.
