Does increasing the voltage across a resistor increase the electric current through the resistor?
Resistance is not affected by either voltage or current. It is determined only by the cross-sectional area, length, and resistivity of the material. As resistivity is affected by temperature, resistance is indirectly affected by temperature.In the so-called 'Ohm's Law' equation, resistance is a constant. So, if you increase voltage, the resistance remains constant, and the current would increase in proportional to the voltage.
How is the brightness of the LED affected by different resistor values?
LED's are light emmitting diodes. diodes have a voltage threshold that must be reached for them to fully "turn on". A resistor can be used to limit that voltage. As the voltage drop across the diode is increased above the turn on voltage (typically .5 - .7 volts), the diode will emmit light. The LED will only light up so far, so by turning the voltage up significantly more will have a very limitted payback in light output.
What is a maximum voltage across a resistor?
The voltage across the resistor is whatever voltage is applied. The only maximum here would be a voltage that would damage the resistor. If you think this might happen, you'll have to look up such a voltage from the data sheets.
What is the voltage across the first ohm resistor?
if R4 is the only resistor (the load), then the drop would be the same as the energy source
If a 100 ohm resistor is needed in an electric circuit carrying a current of 0.3 amperewhat resistor would you select?
A 100 ohm resistor carrying a current of 0.3 amperes would, by Ohm's Law, have a potential difference of 30 volts. A current of 0.3 amperes through a voltage of 30 volts would, by the Power Law, dissipate a power of 9 watts. You need a 10 watt resistor, alhough it is better to use a 20 watt resistor. E = IR 30 = (0.3)(100) P = IE 9 = (30)(0.3)
How would the experimental results be affected if the flask contained moisture at the beginning of the experiment?
test it out
Where would you find a material which is a resistor?
Where would you find a material which is a resistor? You can find a resistor material in Europe
How would a poacher's job be affected if ivory became illegal?
it would not be good because they are not getting paid
How would the Atlantic salmon be affected if the freshwater streams became badly polluted?
The Salmon would become unhealthy
The voltage drop across a resistor is 1.0 V for a current of 3.0 A in the resistor what is the current that will produce a voltage drop of 9.0 V across the resistor?
The resistor is 1/3 of an ohm. A 9 volt drop across the resistor would cause a draw of 27 amps through the resistor. The wattage you would need for that resistor is at least a 243 watts.
When would an airbase commander implement split-MOPP operations?
when post-attack results are analyzed and affected sectors or zones are determined
Ism there 0 ohm resister available in market then its colour coding what?

No power at the blower motor resistor?
Since you're checking the resistor, I would assume you checked the fuse/relay for the blower motor. If not check that. If you have then there would be an open wire between the relay and the resistor.

A 5 ohm resistor a 10 ohm resistor and a 15 ohm resistor are connected in series to a 120 volt power source. What is the amount of current flowing between the 5 ohm resistor and the 10 ohm resistor?
The current would be about 20 volts.
If you adds your sister as a second cardholder to an account will your credit be negatively affected by your sister's bad credit?
No. Only is she became a joint account holder, then both persons credit would be affected if any default occurred.
Why would 1990 fifth avenue gauges quit?
i got this from carfaxRecall date: Not reported Units potentially affected: 7,600 NHTSA campaign number: 86V028000 Defective part or component: ELECTRICAL SYSTEM:INSTRUMENT PANEL:CLUSTER MODULEDescription: A RESISTOR IN THE ELECTRONIC PANEL CLUSTER MAY BE SUBJECTED TO AN ELECTRICAL CURRENT OVERLOAD DUE TO FAILURE OF A SWITCHING TRANSISTOR. CONSEQUENCE OF DEFECT: THE OVERHEATED RESISTOR COULD IGNITE AND START AN INSTRUMENT PANEL FIRE. MODIFY INSTRUMENT PANEL CLUSTER BY REPLACING THE RESISTOR WITH A FUSED RESISTOR THAT WILL NOT IGNITE IF OVERLOADED.
