Why are fixed resisters used in many circuts?
Hi, where there is no need of changing the value of resistor then why do you place variable resistor instead a fixed resistor. After all the selection of resistor depends on the cause of use in application. by the way wide range of resistor values are avilable in the market. if the application requires tuning operation then variable resistor is need to be mounted. nothing is mandatory unless the application requires.

What is the voltage drop running through resistor 1 resistor 1 equals 3 ohms?
There is insufficient information in the question to answer it. You need to provide either the voltage across the resistor, or the power dissipated by the resistor. please restate the question.
What resistor to use to drop 9volt's dc to 6 volt's dc?
To drop a 12 volt source to 6 volts with a resistor, you have to drop 6 volts. The value of the resistor you need would be 6 divided by the current the device pulls in amps. For example, if the device pulls a half an amp the resistor has to be 6/0.5 or 12 ohms. As this device runs on 6 volts and draws 1/2 amp, it's wattage is 3 watts (volts x Amps). Common practice is to double this, or the resistor will probably get too hot and may open. I'd use a 10 watt to resistor to maintain a good margin for safety, and they're readily available. Use a 12 ohm, 10 watt resistor.
Why was there a need for a torch?
people would go bling ! people would go bling !
What ppe would a plumber require when using a blow torch?
They need goggles, overalls and gloves.
What do you need to melt gold?
first you need a good environment to do it in. second you need a torch not a blow torch an acetalyn torch and you need flux to keep from losing any of the gold
What are the basics of how flashlights work?
You need a conductor, power source and a resistor. You need a conductor, power source and a resistor. You need a conductor, power source and a resistor.
When you need to use torch?
You need a torch when you're soldering metals or when you're storming Frankenstein's castle.

Where is the torch you need to use in the cave in poptropica?
You shouldn't need to find it. You should be able to enter the cave and you will be given a torch.
How replace Ford Focus fan resistor?
The fan resistor on the Ford Focus is behind the glovebox. You need to carefully lower the glovebox so you can gain access to the motor, but this can be done without actually removing it, just prise it down gently. Once in, the motor is on the righ hand side as you look in, behind the centre console. Using a torch you shold see the original resistor in place and from here on it should be simple, if a little tight.
Ism there 0 ohm resister available in market then its colour coding what?
Why would you buy something that does absolutely nothing? If you need a "zero ohm resistor", just don't connect any resistor at all.Why would you buy something that does absolutely nothing?

Do you always need a torch at night time?
no
If you have a 12point6V battery and a 9V receiver how can you work out which resistor is needed?
you better not. you need a 9V regulator for this, not a resistor!
How do you calculate the correct resistor value needed using 12vdc to run 6vdc circuit?
You need to drop 6 volts across the resistor. -- The resistor you need is 6/(the current in amps that your 6vdc device uses to operate) ohms. Example: If the device uses 1/2 Amp when it's running, then you need a 6/0.5 = 12-ohm resistor. -- And the power-dissipation rating of the resistor has to be at least 36/resistance watts. Example: For the 12-ohm resistor in the last example, it needs to be a (3-watt or more) resistor.
Do you need a permit to use a blow torch?
In a well managed workplace, you will need a 'hot work' permit issued by the employer, for each operation when using a blow torch.
