Do most electronics run on both 220V and 110 Volts?

Most electronic equipment runs on far less that both of these voltages. Most likely from 5 to 12 volts DC. To get down to these votages it has to be processed by a transformer. Good equipment will have a switch on it so that you can chose what the input voltage will be. All this switch is doing is changing the taps on the primary side of the control transformer. The secondary side of the transformer is the working voltage of the equipment 5 to 12 volts. The secondary side of the transformer is then put through a full wave bridge rectifier to change it to DC. When you charge your cell phone this is all that you are doing when you plug it into the wall, except without the switch to select the 240 volts. The rectifier is built right into the wall PAC and out comes the voltage your cell phone is looking for.

This planet is usually running 120 ac or 220 AC That is what most of the people knows as power. There is and never will be a set of voltages that will run everything. but there are some industry standards personal computer are 3v,5v,12v ,12v. these voltages are not are set but are carefully chosen for efficiency a room heater will take forever to heat a room at 5v. so the conclusion is voltages are chosen for efficiency and nothing more then that.

How does one reduce stray capacitance?

You can reduce stray capacitance by avoiding having long wires running parallel in circuits. Keep wires as short as possible. Long wires running along each other can exhibit stray capacitance effects. Another way is to cut long leads of components such as capacitors and inductors to make them as short as possible. If best, use SM components, as they have no leads which can cause this stray capacitance effect.

What was the purpose of the first battery?

The purpose of the first batery is has been dabated upon for a long time by many smart people (namley the Mythbusters). there is evedance of historic bateries dating back over 600 years. A few theories ( tested by the Mythbusters) medicinal purposes as in hooking them up to Acupunture needles, and to have Godly experiences.Priests could have hoked them up to conductor metals so that people thought they were experiencing a God.

2.4 GHz and bluetooth wireless mouse which one is better?

2.4GHz constitutes the mainstream of wireless mouse, but the popularization of laptops and Bluetooth functions promote a lot the development of Bluetooth mouse. 2.4GHz wireless has the advantage of price, but it also has many advantages such as its effective response range. 2.4GHz also contains a receiver using USB interface, but Bluetooth does not. This brings convenience for Bluetooth users

What does the electronic term Vb mean?

Base voltage in a transistor. There is also Vc (Collector voltage), Ve(Emitter voltage), Ic(Collector current), Ib(Base current), Ie(Emitter current), Vcc(Supply voltage), and Hfe (Forward current gain)

How does a Electronic Drum pad work?

You hit the pad and the electronics sense the impact, usually with an impact force sensor for different volumes, and the signal is sent to the soundboard via wire. On the soundboard there are multiple plug inputs. One for snare, bass drum, cymbols, etc. The "drum" itself doesn't make the noise but rather the input. You could plug a cymbol into the snare input and you would still get a snare sound. The soundboard just senses the initial impact and amplifies it as a drum piece.

Whats wrong with the digsite quest exam 1?

Nothing's wrong with it, would imagine that using a guide to navigate the quest might make it go a bit smoother.

Why scope frequency is always greater then signal frequency in the oscilloscope?

In the course of sampling a signal to graph the parts of a repeating event on the display, the sampling must be done faster than the event you want to graph. If the sampling is done slower than the event then you will be displaying several parts of the event in a single dot on the display, highly inaccurate.

The signal sampling must be done fast enough to display the event in enough detail. The higher you set the scope frequency, the wider the event appears on the display, possibly losing the sides of the event if you go too high.
