Most active electronic devices (devices that amplify or switch states, e.g. vacuum tubes, transistors) only operate when conducting in one direction. If the current reversed periodically (as it does in AC) these devices would either not work at those times or would do something much different than they were designed to do. Thus DC is needed to keep them operating all the time.
What else can I help you with?
Why electronics is important?
It's not. You'll never need it.
What is electronic bottleneck?
Electronic bottleneck refers to the inability of electronic devices to process optical data at very high speeds. The term is used mostly when trying to justify the need to process ultra high speed data using all-optical devices without the need for optical-electrical-optical conversion.
Why low power VLSI technology is preferredover VLSI technology?
Low power VLSI is preferred over VLSI.It is because of the following reasonsIt consumes less power i. e. the power consumption is lowThe power dissipation is also lowmost of the modern devices need to operate at low powerComplex systems can be designed with reliability as the power consumption is low.We use modern electronic devices like mobiles ans robotics. These are generally compact and movable. Hence, they operate with a battery rather than power connection. Hence, we need low power operation.
Advantages of parallel circuit?
A parallel circuit can run several devices using the full voltage of the supply, varying the current to the need of each device. If one device fails, the others will continue running normally. If the device shorts, the other devices will receive no voltage, preventing overload damage.A series circuit divides the supply voltage among the devices with a consistent current. If one device fails, all other devices in the circuit will either fail to receive voltage or receive too much voltage and become damaged in the case of a short.An advantage of parallel circuits is increasing the power rating of the circuit and reducing the resistance.
Do I need more then 70 kVA 3 phase power supply for a 4 sunbeds in a tanning salon?
You don't need three-phase power; tanning beds run on single-phase. You've got enough amps.
What adapter do I need for Japan to ensure my electronic devices are compatible with the power outlets there?
You will need a Type A or Type B power adapter for Japan to ensure your electronic devices are compatible with the power outlets there.
What adapter do I need for Argentina to ensure my electronic devices are compatible with the power outlets there?
You will need a Type C or Type I adapter for Argentina to ensure your electronic devices are compatible with the power outlets there.
What adapter do I need for India to ensure my electronic devices are compatible with the power outlets there?
To ensure your electronic devices are compatible with power outlets in India, you will need a Type D power adapter. This adapter will allow you to plug in your devices and use them safely in India.
How an UPS works?
A UPS (uninterruptible power supply) works by providing backup power to electronic devices in the event of a power outage. It typically consists of a battery that stores power and an inverter that converts the stored DC power into AC power. When the main power source fails, the UPS switches to battery power to ensure continuity of power supply to the connected devices.
What is the difference between electronic devices and electrical devices?
All modern day computers are built using electronic or semiconductor processors and components, so these are electronic systems which of course need electrical power to operate but are not in general put under category of electrical devices.
What type of power adapter do I need to use in Dublin?
In Dublin, you will need a Type G power adapter to plug in your electronic devices.
What adapter do I need for Scotland to ensure my electronic devices can be used without any issues?
To ensure your electronic devices can be used in Scotland without any issues, you will need a Type G power adapter.
What is the syllabus for electronic circuits and electronic devices?
you need to be mo specific.
I am travelling to Aus from Canada and I want to bring my laptop I know the voltage diff of 120 240V between the two All I can find is its an 18.5V DC or 19.0v DC Do I just need the plug adapter?
Check your power supply; the power supplies of most portable electronic devices are labeled for "100 - 240V, 50 or 60 Hz", which is alternating current. All electronic devices themselves operate on direct current, and the 18.5VDC that you are seeing on the laptop itself is from the power supply to the laptop. The power supply "rectifies" the alternating current to direct current, and steps down the voltage to whatever your device requires. So, you probably only need the plug adapter.
What power adapter do I need for Israel?
For Israel, you will need a power adapter that is compatible with Type C or Type H outlets. These adapters are commonly used in Israel for electronic devices.
What FireWire connector must use a separate power supply?
No FireWire does not need a separate power supply to operate. FireWire is used to connect peripheral devices to a computer.
Do you need an adapter for Japan to use electronic devices"?
Yes, you may need an adapter for Japan to use electronic devices due to the difference in electrical outlets and voltage.
