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 much current is in a resistor of 1.8 k if the potential difference across the resistor is 4.0 X 10 V?
22ma. E=R/I
What are the different symbol of resistor?
Put the resistor symbol ie zig zag. Then put a crossing line with arrow headed at the top.
Voltage drop of 15 Volts across 2.7 killo ohm resistor?
You just stated that the voltage across the resistor is 15 volts, so that's your answer ! If the resistor is connected to a 15-V battery or to the output of a 15-V power supply, then a meter across the resistor is also across the power supply, and reads 15 volts. The current through the resistor is (V/R) = (15/2700) = 5.56 mA. The power dissipated by the resistor (and delivered by the battery) is (V2/R) = (225/2700) = 0.083 watt.
What does R T mean on a circuit board?
resistor-thermistor
Which one of the following equations could be used to calculate the power absorbed by a resistor?
p=I*I*R ,P=V*V/R;where I is the current passing through the resistor, and V is the voltage across resistor, and R is the Resistance of the resistor,
What is the difference between RDJ7y and DJ7Y spark plugs and what does the R stand for?
the R stands for Resistor. It is a resistor plug.
What does R mean in an electrical circuit?
it's generally the resistance. its generally the energy dissipiating component called Resistor
What does resistor mean in design and technology?

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.

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.
What do the colours on resistor mean?
It's a code to tell you the value of the resistance of the resistor.
