How Determine the power dissipated by the resistor?

Power dissipated by the resistor = I^2 * R or V^2 / R, where R = its resistance value, I = the current in the resistor, and V = the voltage drop across the two terminals of the resistor. You need to measure or find the information of either I (using an ammeter) or V (a voltmeter).


If resistor X has the same length and is made of the same material as resistor Y but has twice the diameter. Resistor X has the blank resistance of resistor Y?

R = r*L/A where: R = resistance r = material resistivity L = length A = area Since you are doubling the diameter, you are increasing the area by a factor of 4, so Y will have 1/4 the resistance of X.


At what level will typical resistors burn out?

A typical resistor will burn out when it dissipates power in excess of double its power dissipation rating for an extended period of time. The power dissipated by a resistor is equal to I2R or E2/R, where E = the voltage across the resistor I = the current through the resistor R = the resistance of the resistor

How can you work out the power of a resistor?

It depends what you mean by your question. Ohms Law is the key. Power in a resistor is wasted as heat. If a resistor has 1 volt across it and passes a current of 1 amp, it will consume/dissipate one Watt of power ,and must therefore have a resistance of one ohm. To work out the power rating of a resistor required, use V x I = P V is voltage I is current in Amps P is power in Watts R is resistance in ohms V=I X R. I=V/R R=V/I Ohms Law is the fundamental equation of electricity and must be understood before you can go further.


Power delivered by 10ohms resistor and 25volt?

The power dissipated by a resistor is E2/R .If the "25volt" is the potential difference (voltage) between the ends ofthe resistor, then the resistor dissipatesE2/R = (25)2/10 = 62.5 watts .That's quite a fair amount of power ... more than you could expect to dissipatefrom a typical carbon composition resistor. This particular resistor is somethinglike a heating coil in a toaster or a large acquarium, for example.
