Is it ok to give more power than required without a resistor such as a series of LEDs that require 11.6 volts at 100 mA but actually powering them with 11.9 volts?

If you don't add a resistor to drop the additional voltage, you run the risk of burning up the LEDs.

What gauge wire is required to hook up an electric kitchen stove?
Normally a new kitchen stove will require a 50 amp breaker wired with AWG # 6/3 with ground wire.
What resistance value is add to convert a galvanometer into a voltmeter?
It depends on the resistance of the galvanometer and the current required to reach full scale. A 100 ohm meter requiring 1 milliampere would require 99.9 KOhms in series to become a 100 volt voltmeter.
Why does the field winding of a series dc machine has less number of turns than that of a dc shunt machine?
The series winding takes the full load current of the generator. So it require only a few turns to produce the required magnetic field and so the resistance is lower.
What is ammeter sensitivity?
Ammeter sensitivity can be determined by a change of scale for the ammeter which would introduce higher or lower resistance values depending on the reading required. A higher sensitivity for lower values of ampacity would require higher resistance in the measuring circuitry. Use Ohm's law to verify.

What do the fieldwork standards under GAAP require?
The fieldwork standards address what is required when actually performing the audit work.
What is an RC filter for a ripple?
Place a capacitor across the output or load and you have your filter. This assumes that your load is a resistor. The capacitor you use depends on the frequency of the ripple. Lower frequencies require larger capacitors. A resistor may be required to make sure you do not damage any of the electronics either in series with the capacitor or immediately after the power source.
What is the past tense of require?
The past tense of "require" is "required."
What part of speech is the word required?
Require is a verb.
What is required mean?
Required means that you can just require something with a coincidence
Is it true that the higher a resistance value the higher the voltage drop?
Greater value resistor will absorb more voltage than smaller value. The more voltage absorb with same value current flow, the larger body mass resistor will require. Body size depends on type of resistor (material resistor is made of).
Is energy released or required for evaporation?
require.
Can you buy a cheap phone?
Sure. Just be careful, as some supposedly "cheap" phones actually require contracts, and can actually cost quite a lot. Think twice if you're required to sign (or otherise agree to) any contract.
Do car insurance Nebraska laws require me to have full coverage insurance?
In Nebraska, you're actually not required to have full coverage. You'll only need to have minimum liability insurance.
Is the word require a noun?
"Required" could be a verb or an adjective. For instance, to use it as a verb, you could say, "You required him to clean his room." To use it as an adjective, you could say, "This is a required test."
Do you need to put a shunt resistor to connect the ac voltmetr?
Shunt resistors are used with ammeters; voltmeters require series resistors.
What value of resistor would take you from 18v ac to 3.3v ac?
sorry - no can do. The value of a resistor is dependent upon the amount of current flowing through it. To drop the a.c. voltage as you have stated would require a drop-down transformer.
