Basically, when LEDs are connected in parallel, the LEDs with the lowest resistance will be the brightest, the other LEDs will be dimly lit or not lit at all. Therefore, use LEDs with the same model number and colour.

Which resistor is connect 1.5 volt led to series 220v ac?
Typically, a 100 ohm resistor is used to connect a 1.5 volt led to a series 220v ac adapter. Many LEDs can be connected into a string using the resistors.
Why do defective LEDs flash?
Defective leds flash due to the temperature of the chip. When the LED chip is hot, the filament disconnect(the LED light turn OFF) and when it came cold it connect again (the LED light turn ON). It is similar to the bimetallic switch, see: http://www.youtube.com/watch?v=j-JNyFn85rI Try to get a led witch have a better quality.
Why two voltage sources of different voltage rating cannot be connected in parallel what is the coresponding statement for current sources?
Yes of course.. u just need some connecting wires to connect them in parallel
How do you install a resistor in an DC circuit?
It depends on the purpose for installing the resistor. If the intent is to decrease current flow, the resistor must be connected in series with the load. If the purpose is to increase current flow, the resistor must be connected in parallel with the load. To connect a resistor in series, connect the resistor to one side of the power source, in line with the load. This will decrease circuit current flow. To connect a resistor in parallel, connect the resistor between the positive and negative sides of the power source, which will effectively connect the resistor across the load . This will increase current flow through the circuit. However, before connecting a component in parallel, make sure the increase in current flow will not exceed the current rating of the circuit or fuses/breakers will blow.
What is a superflux led?
Superflux LEDs are the pinnacle of LED lighting. At a glance at the specifications it would appear that they are not as bright as the 3mm and 5mm LEDs, however with their 110 degree viewing angles they kick out an enormous amount of light. Making them perfect for vehicle stop lights, signs and many many more applications. Superflux LEDs are also known as Piranha LEDs. http://www.phenoptix.co.uk/Superflux_LEDs_s/35.htm
What happens if you connect two transistors parallel?
If you connect two transistors parallel it will heat up and be damaged.
What size resistor is needed when wiring two leds in parallel using 6 volts dc?
A: LEDS are devices that needs a certain voltage and current typically 1.8 and 20 ma
When do you connect LEDs in series?
A: regular LEDS have along lead and a short lead the longer is usually positive. This lead must go to a positive potential. the shorter lead is less negative which must connect to next led positive and so on as a string.
How do you connect 5 LED rebel star?
Have a common ground and separate the +ve to each of the LEDS
How would you connect several resistances if you wish to increase the current?
Connect it in Parallel.
What is the internal name for the parallel port and what type of devices can you connect to it?
internal parallel port
You want to take 25ams output you are having 16 Nos of 12V 8Ah batteries do you have to connect batteries in series of parallel connection?
Parallel or Series Connections for BatteriesTo increase current [measured in Amperes], you connect batteries in parallel. To increase voltage, you connect batteries in series.
Does a diamond have parallel lines?
NO. A diamond does not have parallel lines. All the lines would eventually connect.
You are building a string of lights using several bulbs how is the brightness of the lights related to whether you connect the bulbs in series or in parallel?
Overall brightness (not individual bulbs' brightness) will increase when we connect them in parallel & it will decrease when we connect them in series.
Can two electric resistors connect in both series and parallel?
yes two resistors can connect both in series and parallel because when you connect two resistors in a closed loop, the same intensity of current flows across them and also they are connected to the same nodes which are the conditions for series and parallel connections respectively.
To construct a battery with a current of 6 amps you would connect six 1 amps cells?
You would connect them in parallel to increase the amerage. If you connect them in series it would increase the voltage. Connected in series-parallel would increase both voltage and amerage.
Which is a more powerful light - 95 leds or 128 leds?
If your compairing apples to apples like 3 watt leds to 3w leds then 128. The more leds the higher the power.
