Is a resistor like a surge protecter?
Not really. They might help a little, but they are not surge protectors
Why use surge protecting resistor to generator rotor winding?
To limit the fault current used surge protective resistance in generator rotor winding to protect the rotor winding heavy damage.
What is a surge suppressor varistor?
A varistor is an electronic component used for surge suppression. It is also known as a voltage dependent resistor, but it acts more like two zener diodes reversed and placed in parallel. The majority of surge suppression devices use these. However, they don't work all that well for lightning strikes.
What is a surge resistor?
A surge resistor is a resistor installed in a circuit to prevent a "surge" when conditions arise where a surge might occur. That might be a bit wordy, but that's the answer. Let's look at an instance where a surge resistor is used and see how it works. There are a number instances where energizing a circuit is followed by a surge of current. Like almost all the time. When that circuit "comes on" after the switch is flipped, current is flowing. And sometimes we need to place a resistor in series with the component or components that want to draw a ton of current on startup. We can look at a component that might just do that. Capacitors (caps) are sometimes fitted with something that limits a big shot of current when a circuit is energized. Caps, you recall, begin operation in the circuit of a modern equipment uncharged, and when these caps are first "seen" by the voltage source at the moment it's turned on, they look like a short circuit. Lots of current may want to flow. Jumping ahead, the cap sits in the operating circuit fat, dumb and happy "using" only a little current after things are going. But at startup, it needs to be checked to prevent it from "sucking up" (or sinking) too much current and overloading the supply. The surge resistor is on the job each time the circuit is energized. There are other applications for a surge resistor, but the purpose is the same - prevent "too much current" from flowing at a given moment so the circuit can transition into a "normal operating mode" (where current flow is more modest). The surge resistor is similar to a so-called current limiting (or, perhaps, ballast) resistor, but the name applied to the resistor in question might have more to do with the specific application.
Can you use a 91ohm resistor in place of 100ohm resistor?
It depends on where you are going to use this resistor and what its application going to be. If the circuit you are using can tolerate this then you are fine.
How could you use surge in a sentence?
I would not go surfing today. There is a storm surge coming. I noticed a surge in the electricity before the light burned out. After drinking coffee, I had a surge of energy.
What resistor should you use to get 9v to 6v?
You can only use a resistor to drop a voltage at a constant current. If you know the current, use Ohm's law to calculate the resistor value.
Is it highly recommended to use surge protectors for computers?
Yes it highly recommended to use surge protectors for computers especially if you live in an industrial area.
How do you use resistor in a sentence?
I installed a resistor inline with my oil pressure sensor. The resistor in a circuit will usually disperse energy as heat.
Can you calculate the resistance of a component using a meter and a resistor?
yes you can! you can use a multimeter and a resistor.
Do surge suppressors work for residential use?
Surge suppressors do work for your residence. They protect your GFIs and appliances. www.geindustrial.com
Why you use 250 Ohm resistor in series with HART protocol communication?
You need to use the 250 Ohm resistor in series with HART protocol communication because it acts as a shunt resistor.
