To understand what is 10k resistor, we first need to grasp the basics of resistors. Resistors are passive electronic components that limit the flow of electric current. They are designed to have a specific resistance value, measured in ohms (Ω). A 10k resistor is a fundamental electronic comp...
17. A 1.0 kQ resistor has a maximum power rating of 0.25 W.What is the maximum rate of flow of electrons that can pass through this resistor? C A 1.0*10^(13)s^(-1) B 1.0*10^(15)s^(-1) C 1.0*10^(17)s^(-1) D 1.0*10^(19)s^(-1) 相关知识点: 试题来源: 解析 C...
Like all components, it is preferable to keep temperatures as low as possible, so no resistor should be operated at its full power rating for any extended time. I recommend a maximum of 0.5 of the power rating wherever possible. Wire wound resistors can tolerate severe overloads for a shor...
theelectric noiseof the resistor must be as low as possible. This is often specified as microvolts noise per volt of applied voltage, for a 1 MHz bandwidth. For high power applications thepower ratingis important. This specifies the maximum operating power the component can handle without alteri...
432.2 of this part: (a) The power line voltage shall be 120 volts AC (230 volts when the equipment is made for foreign sale or use, unless a different nameplate rating is permanently affixed to the product by the manufacturer in which event the latter figure would control), RMS, using ...
One of the terms often found on electrical and other items using an alternating supply, is the term VA. A motor may have a rating in terms of VA rather than watts. The term VA is used as a shortened form to indicate the volts times amps, but without taking regard for the phase diffe...
2.2 k ohm resistor 4.7 k resistor 2 ohm resistor 150 ohm resistor 100k ohm resistor ·Accuracy and Tolerance Applying the resistor’s accuracy rating is the following step. This is the resistor’s accuracy or tolerance level. Carbon resistors are less precise than metal-oxidized resistors. They...
The power amplifier, possibly several of them for a live show, sits in a rack and gets on with its job. The technology is mature and there isn't all that much difference between power amplifiers, so you simply choose a reliable manufacturer and the required power rating. Rack up, and yo...
Lower power ratings:The power rating of surface mount components is of great importance. The surface mount resistor is the particular example. A standard leaded resistor can dissipate at least 0.25 watts. For surface mount resistors, bing much smaller, the dissipation is also less. Be awa...
Maximum power rating: The maximum power rating of a thermistor is the maximum power, expressed in watts or milliwatts (W or mW), which a thermistor will dissipate for an extended period of time with acceptable stability of its characteristics ...
