If you consider the transistor level of a module, active low means the capacitor in the output terminal gets charged or discharged based on low to high and high to low transition respectively.
When it goes from high to low it depends on the pull down resistor that pulls it down and it is relatively easy for the output capacitance to discharge rather than charging. hence people prefer using active low signals.

What is the effect of inductive load in distribution system?
Inductive load where current lags voltage to keep the power factor low thus increasing the consumption of more electrical units of supply provider. This is since an inductive load draws reactive power as well with active power. Reactive component is watt less power drawn from the source. We use only active part of the source. But pays from active+reactive parts. This low power factor also effects the other systems in the circuit virtually making the cables under sized by heating them
Do you need a licenced electrician to hang conduit for low voltage cable?
In most places, for residential, no. For commercial, most jurisdictions require a contractors license for anyelectrical work. Where I live, there is a low-voltage license that is less than a full-blown electrical license that is used by fire alarm, security, and telecommunications contractors. The NEC and most jurisdictions define low voltage as less than 30 volts. Check with your local building department to be sure!
Why humans not listen to very low frequency vibrations?
Most humans are incapable of hearing frequencies slower than about 20 Hz.
What are the advantages of active filters over passive filters?
Active filters have three main advantages over passive filters:Inductors can be avoided. Passive filters without inductors cannot obtain a high Q (low damping), but with them are often large and expensive (at low frequencies), may have significant internal resistance, and may pick up surrounding electromagnetic signals.The shape of the response, the Q (Quality factor), and the tuned frequency can often be set easily by varying resistors, in some filters one parameter can be adjusted without affecting the others. Variable inductances for low frequency filters are not practical.The amplifier powering the filter can be used to buffer the filter from the electronic components it drives or is fed from, variations in which could otherwise significantly affect the shape of the frequency response.
Can a low wattage lamp be used to diagnose simple wiring faults?
Yes, this simple primitive tool is the best diagnostic tool for most wiring problems.
When is lac operon most active?
The lac operon is most active when glucose levels are low and lactose is present.
Does active transport go high to low or low to high?
Well it depends most of the time it goes from low to high.
Why most IC are active low?
Most control signals in electronics are active-low signals (usually reset lines, chip select lines and so on). This stems from the fact that most logic families can sink more current than they can source, so fanout and noise immunity increase. (The reason for this is ultimately related to the fact that electrons are negatively charged.) It also allows for wired-OR logic if the logic gates are open-collector/open-drain with a pull-up resistor. Examples of this are the I²C bus and Controller Area Network (CAN).
In females puberty will be most delayed in those individuals who are?
active and have low body fat
When are bass the most active?
Bass are most active during low-light periods such as early morning and late evening. They tend to be more active in cooler water temperatures and may also become more active during overcast days.
What is the tri state device in microprocessor 8085?
A tri state (bus driver) device is a device that can be active low, active high, or floating. The use of a tri state device is that several of them can be connected to a single bus line and, so long as only one of them is non-floating, the bus line can be driven by multiple senders. The data bus is most often implemented with tri state drivers.
Explain Externally initiated signals and interrupt in 8085?
The 8085 Microprocessor has five interrupts signals that can be used to interrupt a program execution. They are:INTR-Interrupt Request (Input): This is used as a general -purpose interrupt.INTA-Interrupt Acknowledge (Output): This is used to acknowledge an interrupt.RST 7.5, RST 6.5, RST 5.5-Restart interrupts (Inputs): These are vectored interrupts that transfer the program controls to specify memory locations. There have higher priorities than the INTR interrupt. Among these three, the priority order is 7.5, 6.5 and 5.5.TRAP (Input): This is a non-mask able interrupt and has the highest priority.In addition to the interrupts, three pins - RESET, HOLD, and READY - accept the externally initiated signals as inputs. The HOLD signal indicates that a peripheral such as a DMA (Direct Memory Access) controller is requesting the use of the address and data buses. The READY signal is used to delay the microprocessor READ or WRITE cycles until a slow-responding peripheral is ready to send or accept data. When this signal goes low, the microprocessor waits for an integral number of clock cycles until it goes high. Lastly, when the RESET IN signal goes low, the program counter is set to zero, the buses are tri-stated, and the MPU is reset and the RESET OUT signal indicates that the MPU is being reset and used to reset other devices.To respond to the HOLD request, the 8085 Microprocessor has one signal, called HLDA (Hold Acknowledge). It acknowledges the HOLD request.
When is the best time to observe active wildlife at dusk and dawn"?
The best time to observe active wildlife at dusk and dawn is during the hours of low light, when animals are most active.
What animals are most active at dusk and dawn?
Animals that are most active at dusk and dawn are known as crepuscular animals. These include species such as deer, rabbits, foxes, and certain birds like owls and bats. They are adapted to low light conditions and are most active during the twilight hours.
What animals are most active at dawn and dusk?
Animals that are most active at dawn and dusk are known as crepuscular animals. These include species such as deer, rabbits, foxes, and some birds like owls and bats. These animals have adapted to low light conditions and are most active during the twilight hours.
What types of animals are most active at dawn and dusk?
Animals that are most active at dawn and dusk are known as crepuscular animals. These include species such as deer, rabbits, foxes, and some birds like owls and bats. They are adapted to low light conditions and are most active during the twilight hours.
What is the reason for naming microprocessor as 8085 and microcontroller as 8051?
b/c the 8085 microprocessor is the first 8 bit microprocessor which Intel is produces in 1877 and this is the first general purpose 8 bit microprocessor. there was an 8 bit general purpose register before 8085 named as 8008 but this microprocessor is not functional 8 bit microprocessor
