Does the light across the back of a Cadillac CTS lights up?

yes, it lights up only when brake is applied


Can high voltage take out lights?

Yes, a higher than normal voltage that the equipment needs will shorten the life of any device.


When a three light circuit is connected in series with 2 6V batteries what is the voltage across each of the lights?

If a three light circuit is connected in series with two 6V batteries, and the three lights are identical, the voltage across each of the lights is 12V divided by 3, or 4V.


What happens to a voltage as the Christmas lights are connected in series?

Divide the number of lamps into the value of the supply voltage, and that will tell you the voltage drop appearing across each lamp. Bear in mind that if one of the lamps should be removed, the full supply voltage will then appear across the empty lamp holder.


This is a special type of diode that lights up when a small voltage is applied They are usually used as indicators or in numerical or alphanumerical displays?

led


Would the lights be lighter in parallel or series?

The VOLTAGE in a series circuits will be dropped in to the connected lights.So the light after no1 will get much lowyer than the first light.Because voltage drop in first light will cause that problem of light to lighter. But in prallel connection the voltages are divided in to equal levels.So no voltage drops in prallel connection, all lights get full voltage as applied in input mode.SO THE LIGHTS BE LIGHTER IN SERIES CONNECTION.


Who lights brighter bulb in a parallel circuit?

Yes, since each light would get the full voltage. Be careful if you actually carry out this experiment, that the lights don't get too much voltage. If the voltage is (for example) 110 Volts, and the lights are built for 110 Volts, you would have no problem; in a series circuit they would simply get dimmer.because the wires are togetherAnswerNot necessarily. It depends upon the voltage ratings of the lamps, and whether the voltage across each lamp matches their voltage rating.


Why do parallel circuits provide more power to the lights?

With several lights in series across the power source, the full voltage of the power source is divided among the group of lights, in proportion to the resistance of each one, and the power available to each light depends on all of the others. The more lights in the series circuit, the less voltage each one gets, and the less power each can dissipate as light. ============================================ Another contributor added: Furthermore, power = voltage times current, and Current is equal to voltage divided by resistance. Putting lights in series increases the circuits resistance, which lowers the current, thus decreases power. This is why the overall light output of two lights in series will be less than a single light.


If the head lights on a 1987 Nissan 300 ZX stopped rolling up or down should you check the fuses?

Get a multi-meter and check for power at the motor that moves the lights up and down. If there is 12V, your motor is shot. If there isn't 12V then it could be a fuse. Use your multi-meter again to check for voltage across the fuse. If there is 12V across the fuse, the fuse is blown. If there is virtually no voltage measured across the fuse, the fuse is good. You might have other problems. Good luck.


How can you tell if its the battery or alternator that's not working on a car?

Start car. Turn on all lights, blower etc., that you can. Read voltage across battery terminals. If voltage is 13.5 or more then your alternator is okay. This assumes you have clean connections, good cables.


What is it called when one light goes out and the rest are still lit up?

This may apply to lights that are wired in parallelacross a voltage source. In a parallel circuit, like the outlets in a home, the same voltage is applied to each thing that is plugged into the outlet. That way all the appliances can be designed for a constant operating voltage and if one fails, the rest continue to operate uaffectedly. Picture a railroad track as the two sides of the electrical bus. Everything hooked up is attached "across" the rails, and works on the voltage that is on the rails and operates independently of other things across the rails. When we talk about a power bus in electronics, we sometimes refer to the "rails" of the bus - the two sides of the supply.


Why do two lights connected to one switch get dim?

Because when two lights use the same battery, both lights need the same power to work, so the power has to split in half making the bulb's brightness dimmer. Ridiculous. If the lamps are connected in series, they will be dim because half the available voltage is dropped across each lamp. In parallel, they will both have full brightness.
