When a manual refers to a particular resistor as 2.2 megohm resistor does this means the resistor can safely carry a current of 2200000 amperes?
No. It means it has a resistance of 2,200,000 Ohms. Plus or minus the tolerance.
How are the plus and minus voltage signs determined for resistors?
Resistors have no polarity. The voltage across a resistor is determined by the direction of current flowing through that resistor (and vice versa).
A resistor is said to have a resistance of 82105 ohms and a tolerance of 5 percent. What coloured bands should it have?
A 5 percent tolerance resistor would only have two significant digits in its stated value, so we are talking about 82000 ohms plus or minus 5%. The coloured bands would be grey (8), red (2), orange (times 1000), and gold (5%).
What does a 100k resistor do?
Resistance: Electrical resistance describes how an electrical conductor (a wire) opposes the flow of an electrical current (flow of electrons). To overcome this opposition a voltage (a energy) must dropped (used) across the conductor (wire). Resistance can be described by ohms law: Ohms Law: R = V / I (Resistance = Voltage / Current) (resistance measured in ohms) where: Voltage [V]= the energy lost across an component (voltage measured in volts). Current [I] = the charge (electrons) flowing through an component (current measured in Amps). Electrical resistance can be thought of as sticking your hand out a car window. The faster [current] you drive the harder the wind presses [resistance] against you hand and therefore it takes more energy [voltage] to hold your hand steady. When trying to overcome electrical resistance, the electrical energy lost is turned into heat. This is how the elements of a household stove, toaster, and fan heater work. Because of the vacuum in a light bulb, the electrical energy lost is instead turned into light. It can be seen the electrical resistance plays a large role in modern life. Resistor: The resistor is the most common electronic component and is used to limit and/or control the voltage and current in an electronic circuit. Resistors are carefully manufactured to provide a predetermined value of electrical resistance which may range from 0.1 ohms to 100,000,000 ohms, depending on the application. The physical size of a resistor also varies dependant on the amount of power passing through the resistor, given by: P = V x I (Power = Voltage x Current) (power measured in watts) There are also many types of resistors including: · Variable Resistor - changes resistance when its shaft is rotated (volume knob on a stereo). · Thermistor - changes resistance when the temperature changes (used in a thermostat). · Light Dependant Resistor (LDR) - changes resistance when the lighting changes (used in children's night-lights). Resistor Example: An LED is a small red light (such as the one on the front of most TVs) and requires 2.0 volts and 0.02 amps to operate correctly. If we connected that LED up directly to a 12 volt battery, the voltage would be too high, and too much current would flow… the LED would blow up. We need to use a resistor to limit the voltage and current. But which value of resistance should the have resistor? Uses ohms law: R = V / I = (12.0 - 2.0) / 0.02 = 500 ohms (Note: the voltage across the resistor is the battery voltage minus the voltage we want across the LED) But which value of power should the resistor be capable of handling? P = V x I = (12.0 - 2.0) / 0.02 = 0.2 WattsNote: k = x1,000 M = x1,000,000 G = x1,000,000,000So a 10k resistor = 10kohms = 10,000ohms

In automobile it is used in many areas like Body Areas & Cabin Controls, Integrated Drive Train & Starter/Alternators (including 42V systems), DC/DC Converters, Lighting Supplies, Engine Management & Ignition/Injection System and Hybrid/Electric Vehicle.
A resistor is marked with the following color bands brown black red and gold What is the resistance of this resistor?
1000 ohms = 1Kohm; silver is the tolerance band of the resistor. Silver signifies plus or minus 10%. The fourth band is always the tolerance band. If there is no tolerance band, the tolerance is plus or minus 20%. A gold band would signify plus or minus 5%.
When a manual refers to a particular resistor as 2.2 megohm resistor does this means the resistor can safely carry a current of 2200000 amperes?
No. It means it has a resistance of 2,200,000 Ohms. Plus or minus the tolerance.
How do mean deviation from median?
The mean deviation from the median is equal to the mean minus the median.
How is the z-score depicted?
z-score of a value=(that value minus the mean)/(standard deviation)
How do you find out the z-score?
z-score of a value=(that value minus the mean)/(standard deviation)
What is meant by a z-score?
z-score of a value=(that value minus the mean)/(standard deviation)
What is a normal random variable minus its mean and divided by its standard deviation?
It is the Standard normal variable.
What percentage of observations of a normal distribution is represented by the mean plus or minus 1.96 standard deviation?
It is 95%
What does it mean when the standard deviation is 1?
A standard deviation is a statistical measure of the variation there in a population or group. A standard deviation of 1 means that 68% of the members of the population are withing plus or minus the value of the standard deviation from the average. For example: assume the average height of men is 5 feet 9 inches, and the standard deviation is three inches. Then 68% of all men are between 5' 6" and 6' which is 5'9" plus or minus 3 inches. [Note: this is only to illustrate and is not intended to be a real/correct statistic of men's heights.]
What is the value and the acceptable range for a resistor with the following color code Green Red Orange Silver?
52 x 1K ohms + or - 10%. (Plus or Minus is represented by a + sign with a - sign directly under the +) Like this ±
What is the definition of percent deviation?
Percent deviation is the accepted value minus the observed value divide by the observed value multiplied by 100. The formula is useful in deciding how correct the data is that is collected by students.
