What happens when the resistance in a circuit is too high?
95862
it gets hot, which in turn causes more resistance, and it gets even hotter, which causes more resistance.  if there are enough amps, the metal will melt.

An ohm-meter measures the resistance by applying a voltage across the component. The current flowing through the component is measured, and a little bit of Computation of the form R=V/I would give the resistance.  \n\nIf a voltage is already supplied, then the ohm-meter may read erroneously or may even get screw**.

just put a limiting resistor. 60mA and 12V. Limiting resistor =R=(V-Vled)/I. assuming the extreme, 0V for Vled. R=12/6e-2=200ohm. that way the current will never exceed 60mA.

let the resistances be r1 and r2.\nwe know the equation for power'p' is p=V*I\nV-Voltage applied,\nI-current in the circuit,\nby ohms law,\nV=IR\nsubstitute the value of V in power,\nwe get P=I^2*R  \nif the resistances  are in series then the value of R is,\nR=r1+r2.\nso the power dissipated when the resistance in series is,\np=I^2*(r1+r2),\nsimillarly power dissipated when the resistances are in parallel is\np=I^2*((r1*r2)/(r1+r2))

no just its too much power! go ask a mechainic for the best answer! believe me, this happend to me, he told me all the right stuff!

The resistance is increasing at .1785 ohms!!!\n\nJust use the ohm's law\n\n10/56=.1785 that's the resistance\n\nthen multiply the resistance and the current=volts\n\n.1785 x 56 =9.99999volts\n\nThis is the result.\n\nHope this help!!!

In light, resistance of a solar cell goes down.  When resistance goes down, voltage and current go up.

Current drops as the resistance increases. Think of it as a road. As the road gets narrower (resistance increases) the less cars will pass per minute (current decreases)

Since V=IR  (voltage V equals Current I times resistance R), if the voltage doubles, then so should the current...that is unless the resitance is somehow variable, which is not normal - so it tells you the conductor may have undergone some kind of chnage in state.

Ohm's law:   V=RI\nBy changing I you will have V adjust to keep R constant.\n\nIf I goes up, so will V, because it's a direct relation.\n\nTry it with 100 ohm.  You can have\n100=R=V / I=500 volt / 5 amps\n100=R=V / I=700 volt / 7 amps

um, basically, there is no connection between resistance and frequency. there are however some circuits that output a frequency based on a time constant that can be set by a resistor though. if that is what you mean, then we need to know what circuit you are talking about.

If you have a voltage regulator that is poorly designed (or adjusted?) it will overshoot the target voltage then correct and overshoot in the other direction, etc. etc.  Usually there must be some type of feedback in the circuit that accepts small deviations rather than "hunt" for a too precise voltage value.  Hope that helps a little.

No matter what is the voltage rating, isolation or insulation is tested by using "MEGGER".\nThe value should be atleast above 1 Mega ohm in any case

if you wire the subs in a brigde you can drop your ohm load to 3ohms witch some amps perform beter at that load so take your + from both subs and hook it to the brigde channel on the amp and then - of both subs to the negitive brige channel on the amp then you are runing the subs in parlel this has dorped you ohms to 3 but watch you amp it could over heat if it can not go that low some cant

Electrical resistance is that element of electrical circuit which opposes flow of current through it.\n1.Resistance is dependent on the material.Like wood is insulator(ALMOST infinite resistance).\n2.Resistance of a wire having more cross sectional area is less and less cross sectional area is more(i.e. it is inversely propotional to the cross sectional area.)\n3.It is more for more length and less for less length.\n4. Resistance varies with temprature.For metals like platinum it increses with temprature.

You'll have to describe the circuit a little better \n\nAre you adding either the 3.00 ohm or 2.50 ohm (but not both) in parallel with the 4.00 and 3.75 ohm, and need to know the total resistance with either the 3.00 or 2.50 ohm resistor connected?\n\nOr are BOTH the 3.00 AND the 2.5 ohm being placed in parallel with the 4.00 and 3.75 ohm?\n\nAnd without knowing the applied voltage, your first question (current through a 3.00, 4.00, 3.75, 2.50 ohm resistor) can't be answered.

B. the current will increase
