A resistor is a passive two-terminal electrical component that implements electrical ... time or operating voltage. ... long-term stability (1 year) 25 ppm, (3 years ...
A standard TTL input at logic "1" is normally operated assuming a source current of 40 μA, and a voltage level above 2.4 V, allowing a pull-up resistor of no more than 50 kohms; whereas the TTL input at logic "0" will be expected to sink 1.6 mA at a voltage below 0.8 V, requiring a pull-down resistor less than 500 ohms. [2]
For example, a 10 ohm resistor connected in parallel with a 5 ohm resistor and a 15 ohm resistor produces 1 / 1/10 + 1/5 + 1/15 ohms of resistance, or 30 / 11 = 2.727 ohms. A resistor network that is a combination of parallel and series connections can be broken up into smaller parts that are either one or the other.
For example, 8K2 indicates a resistor value of 8.2 kΩ. Additional zeros imply tighter tolerance, for example 15M0. When the value can be expressed without the need for a prefix, an "R" or "F" is used instead of the decimal separator. For example, 1R2 indicates 1.2 Ω, and 18R indicates 18 Ω.
As an introduction to the next chapter, this figure shows that the term "shunt resistor" should be understood in the context of what it shunts. In this example the resistor R L would be understood as "the shunt resistor" (to the load L), because this resistor would pass current around the load L. R L is connected in parallel with the load L.
Making the switch to a new car insurer can sound daunting at first, but you could be missing out on more than $450 in savings a year by staying with your current carrier, according to a recent ...
Two-way: A simple on-off switch: The two terminals are either connected together or disconnected from each other. An example is a light switch. SPST-NO. Form A [4] Single pole, single throw, normally open A simple on-off switch. The two terminals are normally disconnected (open) and are closed when the switch is activated. An example is a ...
Insurance carriers commonly consider anything over 18,000 per year high mileage use, which can drastically increase the rate of your car insurance. The national average car insurance rate is ...
